This comprehensive kit includes both belts, belt tensioners, upper and lower deflection pulleys, and the adjusting pulley. Select from all Genuine BMW parts or a combination of OEM/OE BMW parts. Staying on top of your belt maintenance is the smart move. Cracked or worn belts are a recipe for a headache or worse. The main drive belt runs critical components - the alternator, water pump, and power steering pump. The pulleys contain bearings that may be worn when it comes time to replace the belts. You can check the pulleys by relieving tension on the belt and feeling each pulley for play or grinding. The tensioner also sees similar wear. If your pulleys are new or don't need replacement, you can pick up the belts on their own.

If your valve cover is leaking oil or a bad seal is causing vacuum issues and check engine lights, we recommend replacing your seals with this complete valve cover gasket kit! This kit includes all of the main gaskets and o-ring seals used by BMW to seal your valve cover to the cylinder head. Included: Victor Reinz Left & Right Valve Cover Gaskets Genuine BMW Oil Separator Seal O-rings - Two Per Valve Cover Genuine BMW Crankshaft Position Sensor O-Rings - Two Per Valve Cover URO Spark Plug Tubes w/ Gaskets If you are not replacing your valve cover, we also recommend inspecting the grommets found on the valve cover bolts. Over time these can compress or split, leading to insufficient sealing of the valve cover to the cylinder head due to a lack of pressure. BMW does not offer these grommets separately from their individual valve cover bolts, but NRW Design came in clutch with their Silicone Valve Cover Grommet Kit.

NOTE: This is a Dry kit and does not include engine oil. See our catalog for all engine oil options! Includes everything needed for a rod bearing service, featuring BE Bearings upgraded rod bearings. The S65 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine. Kit includes Upper and lower BE Bearings upgraded rod bearings Hardware Oil filter Oil pan gasket RedLine assembly lube

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!

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades. Kit Features and Contents: Vargas Turbo Crank Bolt Capture Vargas Turbo Crank Seal Plate OEM Accessory Belt OEM Belt Tensioner & Idler Pullies Liqui-Moly Longtime High Tech Engine Oil (5w-30) - 7 Liters OEM Hengst Oil Filter OEM Oil Filter/Cooler Housing Gaskets TMS Oil Change Sticker Genuine BMW Full-Strength Coolant - 1 Liter

*Includes spark plugs that are two steps colder. We recommend these for cars that will be track driven only*

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

Maintaining your BMW E6X, E8X, E9X, or Z4 engine health is paramount to ensure optimal performance and longevity. Two crucial components that require periodic attention are the cam bearing ledge and valve cover gasket. Regular servicing of these components, along with other critical elements such as the camshaft O-ring, chain tensioner (with gasket), and oil filter, is imperative to keep your BMW running smoothly. Included in Kit: 1 - Cam Bearing Ledge - Exhaust 29 - Torx Bolt 1 - Genuine Cam Bearing Ledge - Intake 1 - Genuine Cam Bearing Ledge - Exhaust 1 - Valve Cover Gasket 4 - Genuine Camshaft O-rings 7 - Genuine BMW TwinPower Turbo 5W-30 Engine Oil 1 - Assembly Lube 1 - Chain Tensioner - With Gasket Ring 1 - Hengst Oil Filter 2 - Collar Screws Cam Bearing Ledge: The cam bearing ledge is vital for proper camshaft support and lubrication. Over time, wear and tear can compromise its effectiveness, potentially leading to camshaft damage. Servicing this component ensures that your camshaft operates optimally, preventing costly repairs. Valve Cover Gasket: A well-maintained valve cover gasket is essential to prevent oil leaks and maintain proper sealing in the engine. Ignoring gasket issues can lead to oil contamination, loss of engine performance, and even engine damage. Camshaft O-Ring: The camshaft O-ring helps maintain proper oil pressure and prevents oil leakage. A deteriorated O-ring can result in oil seepage, leading to lubrication issues that affect engine performance and longevity. Chain Tensioner (with Gasket Ring): Proper timing chain tension is crucial for engine synchronization. Servicing the chain tensioner and its gasket ensures correct timing, preventing potential engine misfires and damage. Oil Filter: Regularly replacing the oil filter is fundamental to maintaining clean engine oil. Clean oil is essential for lubrication and heat dissipation, safeguarding the engine against wear and tear. Kit is for these BMW models: E60 / E61 - N54 3.0L E82 / E88 - N54 3.0L E90 / E92 / E93 - N54 3.0L Z4 - N54 3.0L

Timing chains can cause catastrophic problems with your N52 engine if it doesn't function properly. Common symptoms of failure include excessive vibration or “slap” from the timing chain, and the possibility of plastic particles throughout the oil. Symptoms typically begin to surface between 80,000 and 100,000 miles. If left untouched, the issue can compound itself so far as to allow the timing chain to jump out of time, leaving you with a potentially damaged head and larger repair costs. This kit has been assembled using genuine BMW and high quality aftermarket components. From new timing chain guides, to a replacement oil pan drain plug, this kit has you covered to assure that all the needed parts are on hand and ready to install.

When it comes to optimizing the performance and longevity of your BMW N55 or S55 engine, few upgrades can rival the impact of replacing the camshaft, bearings, and gaskets. These essential components play a pivotal role in your engine's overall health and performance, and upgrading them can deliver a host of benefits, from increased power to enhanced reliability. In this article, we'll explore the advantages of investing in these critical upgrades for your BMW N55 or S55 engine. Improved Performance: Upgrading your BMW N55 or S55 engine with a new camshaft can significantly boost its performance. A high-quality camshaft can optimize valve timing, leading to improved airflow and combustion efficiency. This, in turn, results in increased horsepower and torque, providing you with a more exhilarating driving experience. If you're seeking that extra punch when you hit the gas pedal, a new camshaft is the way to go. Enhanced Durability: The camshaft, bearings, and gaskets are fundamental components of your engine's internal structure. Over time, wear and tear can cause these parts to degrade, potentially leading to catastrophic engine failure. By replacing these components with high-quality, performance-oriented alternatives, you're not only increasing horsepower but also reinforcing the engine's durability. This can help prevent costly breakdowns and extend the life of your BMW engine. Optimal Efficiency: Efficiency is a key factor in engine performance. Worn-out bearings and gaskets can lead to oil leaks and reduced engine efficiency. Replacing them ensures a tighter seal, minimizing oil leaks and maintaining the proper lubrication for all moving parts. This leads to better fuel efficiency and a smoother, more reliable engine operation, all while reducing maintenance costs in the long run. Increased Resale Value: Investing in high-quality components like camshafts, bearings, and gaskets not only enhances your driving experience but also adds value to your BMW. When it's time to sell or trade-in your vehicle, potential buyers or dealerships will recognize the value of these upgrades, making your car more desirable and potentially increasing its resale value.

The S65 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or rod bearing service!

Turbo maintenance has become part of our daily lives here. Our Service department does several turbo overhauls, wastegate adjustments, carbon cleaning, and upgrades every week. For the DIY owner, however, having a complete overhaul kit takes some of the stress out of 335 turbo replacement and this kit includes all of the basic items. It's highly likely N54 turbos will have to be replaced before 100,000 miles. Signs of a failing turbo are high oil consumption and blue smoke from exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems the turbos need to be replaced. 

This package uses new (not rebuilt) Mitsubishi turbochargers (the original supplier to BMW). These are essentially direct replacement turbos but we went straight to the manufacturer instead of going through BMW. They are the same as the factory turbos but without a BMW logo so you save yourself a few hundred dollars. It includes everything that needs replacement during a 335 N54 twin turbo overhaul -

  • Front and rear new OEM Mitsubishi turbos (the original supplier of BMW turbos)
  • 1 gallon of Genuine BMW coolant
  • ​16 - ASA M7x39 studs
  • 16 - Flange nuts
  • All required gaskets and o-rings
  • Water pump install hardware
  • Replacement vacuum hose
  • T-bolt clamps

These are brand-new turbos so a core charge does not apply.

The N55 in your BMW is an interference engine, meaning that if the timing chain were to fail your engine would suffer catastrophic damage due to valvetrain components colliding with each other. Over time the timing chain will start to wear and stretch, potentially causing it to skip timing or just completely fail. Also, the timing tensioners themselves could fail! Early symptoms of timing chain wear include front end noise not associated with VANOS, or slapping noises coming from the timing cover. Turner Motorsport has assembled a complete kit that includes everything necessary, as well as small hardware, to completely service the timing on your N55. Tools needed to do the job can be found on our site as well.

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

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! 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.

2006 E90 330i 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 'high-output' N52B30O0 engine in the 330i. 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.

2007-2010 E90/E92/E93 335i N54 Stage 1 Performance Package with aFe Dual-Cone Intake
Peak Power Gain: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone 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 on the N54 motor. 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 maps (91 or 93+ octane fuel). 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!

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.

Crankcase Oil Separator and Vent Hose Kit - E90 325xi/330xi, E60 525x...

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
