2001-2006 E46 325i/Ci/Xi/iT (M54 engine) Stage 1 Performance Package
Peak Power Gain: +8hp / +8ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

2001-2006 E46 325i/Ci/Xi/iT (M54 engine) Stage 1 Engine Upgrade includes:
aFe Cold Air Intake (filter, heat shield, intake tube)
Shark Injector performance software

Applications:
2001-2006 E46 325i sedan, 325Ci coupe and convertible, 325Xi sedan, 325iT wagon, 325XiT wagon ( M54 engine only).

2007-2010 E60 535i/535xi Stage 1 Performance Package
Peak Power Gain: +65hp / +99ft-lbs
Octane: 91 or higher

Our Stage 1 kit features a cold-air intake kit and performance software for a staggering increase in power and torque. We offer this package with the aFe Dual Cone Intake (DCI) to open up the breathing. The larger surface area of the filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase from low-mid RPM is sensational.

We have paired the aFe DCI with the Cobb AccessPort performance software. The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1 Performance Package is aligned with the Cobb Stage 1 tuning map. Simply plug it in, select the Stage 1 map with your octane preference, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. This Stage 1 package is a great 'bang for the buck' upgrade - this power kit makes more power and torque at every RPM and makes a fantastic snarling sound every time you dip into the throttle. Note that peak power gains are quoted above but this package has even bigger performance gains in the lower RPM!!

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug. To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance! Included in this kit: 8 OEM NGK Spark Plugs 8 URO Ignition Coils 2 AGS Spark Plug Boot Dielectric Grease

Featuring BFI Stage One 65A Billet Aluminum Engine Mounts and Installation Hardware!

From the factory, all BMWs utilize soft rubber or fluid-filled engine mounts. Not only are these mounts prone to degradation, they also allow ample movement of the drivetrain. This translates to looseness in your driveline, commonly associated with missed shifts and a generally isolated feeling.

To improve upon this issue, Black Forest Industries designed these upgraded mounts from the ground up. Their stage one mounts feature a proprietary 65A durometer bushing and bracket/cup design. Maximizing bushing area while minimizing vibration gives this mount the advantage of having the best ride characteristics possible from a urethane mount.

To aid in replacement, the enthusiasts at Turner Motorsport have packaged these mounts with all associated hardware. This ensures a smooth and comprehensive installation, free of stress caused by broken or lost hardware!

Features:

Perfect fit: Utilizing laser-scanning technology permits seamless integration with the factory engine mount arms. Quality tooling: All bosses are matched replicas with stock locations, and all tool clearances and specs are maintained. Heavy-duty construction: The use of billet aluminum instead of cast creates a mount that is dramatically stronger than its factory cast-construction counterpart. Performance design: 65A durometer bushings are geared toward the spirited driving enthusiast who wants better control over motor movement without sacrificing excessive vibrations. Choose BFI Stage 1 for a quality mount that eliminates drivetrain movement without adding excessive NVH.

2007-2010 E90/E92/E93 335i N54 Stage 1 Performance Package with aFe Dual-Cone Intake
Peak Power Gain: up to 107hp / 110ft-lbs
+ aFe Pro5R SI Sealed Intake
+ Cobb AccessPort programmer


Our Stage 1 kit features a cold-air intake kit and performance software for a staggering increase in power and torque. This premium package is offered with the aFe Elite Intake and Cobb AccessPort tuner. The Elite intake kit completely maximizes airflow - drawing in air from grille-mounted ducts for a 'ram-air' effect. Each duct flows through a channel into the airbox where it meets a aFe Pro5R filter designed especially for this application. This is our favorite system for the 335 as it is very well engineered, fits well, and almost looks factory. There are no open filter elements to get loaded with dirt. The kit is supplied complete with an aFe Pro5R filter, airbox, intake tube, sealing materials, hardware, and install instructions. The torque increase from low-mid RPM is sensational.

We have paired the aFe Elite with the Cobb AccessPort performance software. The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1 Performance Package is aligned with the Cobb Stage 1 tuning map. Simply plug it in, select the Stage 1 map with your octane preference, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock!

2007-2010 E90/E92/E93 335i N54 Stage 1+ Performance Package
Peak Power Gain*: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone Intake
+ Wagner Front Mount Intercooler
+ Cobb AccessPort programmer


More power = more heat. It's easy to make more power one time but to continue making that power consistently requires careful planning and design. With the additional boost the air entering the engine is also warmer, making the intercooler more important than ever. In testing, the stock BMW intercooler was quickly overwhelmed and cannot keep the intake air cool enough. The engine computer recognizes that and dials back the boost. A more efficient intercooler will keep boost levels up, delivering consistently higher boost levels. The Stage 1+ package includes a Wagner Evo I plug and play intercooler upgrade. We get great feedback from our customers and technicians about the Wagner FMIC - it's a direct bolt in part using all of the factory piping and it offers 85% more surface area than the factory intercooler.

The aFe Dual Cone intake and Cobb Accessport programmer complete the Stage 1+ package. The larger surface area of the aFe cone filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase and sound from the open intake from low-mid RPM is sensational.

The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1+ package lines up with the Cobb Stage 1 tuning maps for an intake and FMIC (91 or 93+ octane fuel). Simply download the Stage 1+ map from the Cobb website, plug it in, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. The addition of the larger intercooler makes Stage 1 more enjoyable and won't let you down at the track or dragstrip. * Note that peak power gains are quoted remain the same as Stage 1 but the cooler intake air means there is less of a chance the engine computer will cut power from heatsoak.

This item fits the following BMWs:
2007-2010 E90 BMW 335i 335xi 335i xDrive - Sedan

1999-2000 E46 328i/Ci Stage 1 Performance Package
Peak Power Gain: +14hp / +11ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

1993-94 E36 325i/is Stage 3 Performance Package
Peak Power Gain: +40hp / +32ft-lbs
Rev limit: 7000
Octane: 91 or higher

Our Stage 3 kit features a cold-air intake kit, cat-back exhaust, performance software, and is tuned for stock M3 cams (not included in Package, can be added below). This whole package has been precisely tuned to work together and make the most power with as little downside.

The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

We can supply this Package with either a Borla or Corsa exhaust system. Both are stainless steel cat-back sections with dual tips. The Borla is a little more mellower sound than the Corsa. The Corsa makes a deep, aggressive burble that is a bit on the loud side but not over-the-top. Both are very light weight with the Borla weighing only 28lbs.

The difference between Stage 2 and Stage 3 is that the software we supply is also tuned for the M3 camshaft upgrade. Adding the stock cams from the S50 and S52 M3 engine is a big wake-up call on the 325i motor. You can expect big power gains in the top end. The M3 cams are a perfect blend of power and driveability - you lose almost nothing in low-end torque.

Our TMS Performance Chips include specific tuning for each part of the Package. The chip is the safest and easiest way to get big power from your engine. Our chips require premium fuel (91 or higher) and allow us to alter the settings on the engine management. Because we can be more aggressive in our tuning, we can get a lot of horsepower for very little money.

Related Upgrades: Within any Stage, we recommend our Underdrive Power Pulley Kit. The Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

1993-94 E36 325i/is Stage 3 Performance Package includes:
aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)
Borla or Corsa Exhaust
TMS Stage 2 Performance Chip (tuned for intake, exhaust, M3 cams)

E36 M3 Camshafts
We sell this Package without cams. Used M3 cams can be found from various sources (eBay, forums, etc). We can supply you with new, factory M3 cams or the Schrick equivalent (same specs as factory M3). Select one of these options below.

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:
  • 11617531423, Genuine BMW oil separator
  • 11617559530, vent hose
  • 11157522931, oil separator hose
  • 11157567801, return hose
  • 11157537701, extraction hose
  • 11617547242, intake manifold gaskets (set of 6)
    The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

    The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

    This kit fits the following BMWs:
    -10/2005 E90 BMW 325xi 330xi - Sedan
    -10/2005 E91 BMW 325xi - Wagon
    -10/2005 E60 BMW 525xi 530xi

    2006 E90 325i Stage 1 Performance Package
    Peak Power Gain: +29hp / +29ft-lbs
    Rev limit: 7000
    Octane: 91 or higher

    Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

    Our flash software is tuned especially for a cold-air intake, maximizing the potential and providing smoother power delivery. We take the stock software and make adjustments for 91 octane (stock software is set around 87). We can get more power and torque, and increase fuel efficiency without affecting driveability or the life of the engine. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

    Our software fully maximizes the 'low-output' N52B30 engine in the 325i. Our software has been carefully developed on the dyno and the road to provide optimal power and torque gains at all RPM. We change the fuel, Valvetronic, and VANOS maps as well as revise the factory torque limiters. We have paid particular attention to increasing low and mid-range torque. The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

    There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

    Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.
    Turner Flash DIY tool - higher upfront cost but files are emailed back and forth. No downtime - you can still drive the car while we process your tune. Files are emailed back and forth - your stock file comes to us, a tuned file is returned to you. Easy install via Windows laptop.

    The factory boost solenoids, also known as pressure converters, are a common issue on the M57 engine. The vacuum hose also hardens over time due to heat, and can crack or split, leading to vacuum leaks. These failures result in a loss of power, limp mode, lazy throttle response, and check engine lights. This basic kit includes two replacement boost solenoids to restore engine power and performance, plus new silicon vacuum hose that will last much longer than the OE rubber vacuum hose.

    2008-2010 E82 135i N54 Stage 1 Performance Package with aFe Dual-Cone Intake
    Peak Power Gain: up to 107hp / 110ft-lbs
    + aFe Pro5R SI Sealed Intake
    + Cobb AccessPort programmer


    Our Stage 1 kit features a sealed cold-air intake kit and performance software for a staggering increase in power and torque. This premium package is offered with the aFe Sealed Intake (SI) kit and Cobb AccessPort tuner. The larger surface area of the filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. While the new intake plenum box completely seals out the filter from underhood temperatures. The kit is supplied complete with an aFe Pro5R filter, airbox, intake tube, sealing materials, hardware, and install instructions. The torque increase from low-mid RPM is sensational.

    We have paired the aFe SI with the Cobb AccessPort performance software. The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1 Performance Package is aligned with the Cobb Stage 1 tuning map. Simply plug it in, select the Stage 1 map with your octane preference, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

    We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. This Stage 1 package is a great 'bang for the buck' upgrade - this power kit makes more power and torque at every RPM and makes a great sound every time you dip into the throttle.

    1993-94 E36 325i/is Stage 2 Performance Package
    Peak Power Gain: +30hp / +28ft-lbs
    Rev limit: 7000
    Octane: 91 or higher

    Our Stage 2 kit featuring a cold-air intake kit, cat-back exhaust, and performance software. All three of these pieces have been precisely tuned to work together and make the most power with as little downside.

    The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

    We can supply this Package with either a Borla or Corsa exhaust system. Both are stainless steel cat-back sections with dual tips. The Borla is a little more mellower sound than the Corsa. The Corsa makes a deep, aggressive burble that is a bit on the loud side but not over-the-top. Both are very light weight with the Borla weighing only 28lbs.

    Our TMS Performance Chips include specific tuning for each part of the Package. The chip is the safest and easiest way to get big power from your engine. Our chips require premium fuel (91 or higher) and allow us to alter the settings on the engine management. Because we can be more aggressive in our tuning, we can get a lot of horsepower for very little money.

    Related Upgrades: Within any Stage, we recommend our Underdrive Power Pulley Kit. The Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

    1993-94 E36 325i/is Stage 2 Performance Package includes:
    aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)
    Borla or Corsa Exhaust

    Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug. To start over fresh with all new components, we now offer these Ignition Service Kits.

    1999-2000 E46 323i/Ci Stage 1 Performance Package
    Peak Power Gain: +17hp / +8ft-lbs
    Rev limit: 7000
    Octane: 91 or higher

    Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is made with heat-blocking materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe uses an oiled cotton filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

    The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

    Both of these items are packaged and work together. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice (TMS Underdrive Pulleys would also be on that list).

    Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

    We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E46 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

    1999-2000 E46 323i/Ci Stage 1 Performance Package includes:
    aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)

    Glow plugs are located similarly to spark plugs on gasoline engines, and have a similar function. Whereas a spark plug transmits an electrical charge to ignite fuel in the combustion chamber, the glow plug simply works like a heater to warm the combustion chamber. On days when your engine is too cold to start by itself, electricity will flow through these plugs, generating enough heat for them to glow. Without properly working glow plugs your vehicle may be a nightmare to start when cold. This kit contains 6 OEM Bosch Glow Plugs, the same plugs that were installed in your BMW from the factory but without the BMW markup.

    Our Stage 1 kit features a cold-air intake kit and performance software for a staggering increase in power and torque on the N54 motor. We offer this package with the aFe Dual Cone Intake (DCI) to open up the breathing.

    Maintaining the peak performance and reliability of your BMW N52 engine is essential for a smooth and enjoyable driving experience. One of the most effective ways to achieve this is by replacing critical components like the valve cover, crankcase vent hose, angle connector with heating element, and cylinder sleeve. In this article, we'll delve into the numerous benefits of upgrading these vital parts, ensuring your BMW N52 operates at its best. Optimized Engine Performance: Replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve enhances your BMW N52's engine performance. The valve cover plays a crucial role in sealing the engine, preventing oil leaks and ensuring optimal valve operation. When you upgrade these components, you reduce the risk of performance-robbing oil leaks and maintain precise valve timing, resulting in improved horsepower and torque. Enhanced Reliability: Reliability is paramount for any BMW owner. These components, when aged or damaged, can lead to severe engine issues. By replacing them, you significantly reduce the likelihood of unexpected breakdowns or costly repairs, ensuring your BMW N52 engine runs smoothly and reliably for years to come. Improved Fuel Efficiency: An efficiently operating engine not only performs better but also consumes less fuel. The replacement of these components leads to better combustion, reduced emissions, and ultimately improved fuel efficiency. This means fewer trips to the gas station and a lighter environmental footprint. Reduced Maintenance Costs: Regular maintenance and repairs can add up over time. By proactively replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve, you mitigate the risk of more extensive engine damage that could lead to expensive repairs down the road. In the long term, this can translate into significant cost savings. Extended Engine Lifespan: The longevity of your BMW N52 engine is directly tied to the quality and condition of its components. When you invest in high-quality replacements, you're effectively extending the lifespan of your engine. This not only preserves the value of your BMW but also allows you to enjoy its performance for years to come. Precise Temperature Control: The angle connector with heating element is vital for maintaining optimal engine temperature, especially in cold weather. A malfunctioning or worn-out connector can disrupt temperature control, affecting engine performance. Replacing this component ensures consistent and precise temperature management. Customized Upgrades: When replacing these components, you have the opportunity to choose high-performance or specialized alternatives, allowing you to customize your BMW N52 to your preferences. Whether you prioritize power, efficiency, or specific driving conditions, there are options available to tailor your engine's performance accordingly. Included in the BMW N52 Valve Cover & PCV Valve Refresh Kit: 6 Cylinder Sleeves 1 Alternator Mounting Screw Set 1 Angle Connector with Heating Element 1 Valve Cover - Gasket Included 1 Crankcase Vent Hose
