The M54 engine has well-documented issues caused by harmonics. The extreme vibrations cause the weak oil pump shaft to shear off or the oil pump nut to come loose and fall off, all of which results in an instant loss of oil pressure. Achilles Motorsports decided to develop a solution to fix all of these known issues. Achilles takes their oil pump shafts to the extreme, using only the toughest materials and heat treatment processes to ensure optimum strength. The core of this kit is a hardened Chromoly shaft that is centerless ground to ensure absolute trueness. The shaft is engineered with an exclusive square key lock system that not only prevents the gear from ever spinning on the shaft but also adds strength to the area to which the gear mounts. Achilles Motorsports then replaced the pesky oil pump nut with an extended length bolt that is EDM drilled for safety wire to properly secure it for all conditions. Don't wait for your oil pump to fail and leave you stuck with costly engine repairs! Key Features: Hardened Chromoly centerless ground shaft EDM Drilled Bolt with a piece of safety wire included Grade 8 extended length hardware to secure the gear to the shaft Left hand threaded to prevent it from unexpectedly coming loose Exclusive Square key lock shaft and drive gear 100% serviceable & rebuildable without the need for grinding NOTE: Professional installation required! The shaft requires being pressed into the oil pump's inner rotor.

SpecE46 Legal! The Achilles Motorsports Oil Pan Baffle was designed and manufactured to be used on racing, high-performance track, and street driven cars. Each baffle is precision laser cut from .090" heat-treated aluminum then hand-assembled and test fit to ensure accuracy and ease of installation. Achilles Motorsports' baffle design incorporates dual trap doors and a unique oil deflector that prevents oil from splashing out of the sump under hard braking. Together, these help minimize the sloshing of the oil inside the oil pan and keep oil accumulated around your pickup tube. The factory BMW oil pan doesn't do a very good job of keeping oil accumulated around the oil pick-up tube in high g-force situations. By keeping oil accumulated around the pickup tube you can eliminate the costly loss of oil pressure and potential damage to other vital engine parts commonly caused by high g-forces from hard acceleration and braking and high-speed cornering. Professional welding is required for installation! For use with BMW oil pan: 11131432703 During installation, while the oil pan is removed, we HIGHLY RECOMMEND upgrading your factory oil pump with the Achilles Motorsport Upgraded Oil Pump Shaft Kit (T#1150773). After numerous instances of sheered-off oil pump shafts and oil pump nuts coming loose, resulting in an instant loss of oil pressure, Achilles decided to come up with a solution - Don't let it happen to you!

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!

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

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!

See kit contents below for a complete list of included components.

This kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually. This kit includes an updated hydraulic alternator tensioner for added reliability and longevity.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. When you’re racing with an M54 and you want to control oil burn, installing an external catch tank is a great way to do it. The stock oil separator allows oil into the intake at sustained high RPM. This causes the intake runners, piping, and throttle body to be contaminated with oil and carbon build up. Excessive carbon build-up on valves, piston crowns, combustion chambers and spark plugs. This also increases the chance of detonation and power loss. Includes all hardware and parts to make installation easy!

Achilles Motorsports uses an extremely hi-tech Dry Film Lubricating process that will keep friction to a minimum allowing your engine to rev faster without worry while keeping oil temperature lower. Perfect for high-performance street, sprint, or endurance racing engines, this specialized coating protects vital engine bearings on dry engine starts and during extreme temperatures and high RPM operation. This specialized coating is the same process that is the choice of professional engine builders around the world, used on all NASCAR, ALMS, and Grand-Am engines. Achilles' bearings provide increased insurance against mechanical thermal breakdown compared to the OEM type bearing, showing much less wear during routine inspections. Note For high-performance and racing engines, we strongly recommend upgrading the OEM type connecting rod bolts to an ARP Connecting Rod Bolt Set to keep your bearing and caps tight even under the most extreme conditions, eliminating potential walk and bearing problems. As with all racing and performance bearings, professional installation is required. Please check all clearances as per the manufactures specifications.

Stainless steel filtration is not a new technology but is quickly gaining popularity in the automotive segment. With the ability to filter down as small as a paper filter element with the ability to be washed and reused!

The K&P Engineering filter element is made from medical grade, type 304 stainless steel micronic filter cloth to provide unmatched protection against oil contamination and resultant engine damage. A one inch square of this material flows an incredible 1.9 gallons of oil per minute at only 1 PSI pump pressure. The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above normal engine operating temperatures. A super strength nickel-plated neodymium rare earth magnet is installed in the top of the element for magnetic pre-filtering of the oil. The sophisticated bypass is engineered for proper differential pressures and consistent operation, delivering a greater percentage of filtered oil while being very easy to clean. The twist lock design assures positive filter element placement and allows for easy disassembly, inspection, and cleaning. The quad-ring gasket doubles the seal between the filter and the engine. Finally, the filter housing is carved out of solid 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat.

K&P Engineering manufactures stainless steel filters for a vast array of engines around the world. Staying at the forefront of design and testing allows this company to offer a top-tier product for your European vehicle.

Features:

  • Consistent filtering across entire filter surface
  • Superior ASTMF316 filtration performance
  • 7 times the flow of comparable paper oil filters

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!

This kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually. This kit includes an updated hydraulic alternator tensioner for added reliability and longevity.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's own M54 E46 Oil Pan Baffle. Under racing and track conditions, oil can move in the oil pan enough to cause extended moments of oil starvation. This can cause premature, and in some cases immediate, engine failure. This baffle keeps the oil at the pick up better than others on the market. This pan features a tight fit with an extra tab on the front to keep oil from exiting under braking. Six gated holes control oil slosh in the sump. A must have for all track cars. Features and Benefits Track-proven to prevent oil starvation Directional trap door baffling completely that closes off the oil pump pickup for maximum protection against oil starvation during turning or acceleration Baffle plate with drain-back slots help accelerate return of oil to the bottom of the sump while also preventing oil slosh and reducing oil consumption Reduces the risk of oil starvation when oil levels are low Works with the factory cast aluminum oil pan, which is considered a structural member of the engine block and is less prone to failure or leaking than aftermarket sheet metal pans Light-weight aluminum construction Made In the USA **Note: Requires welding to install.

Stainless steel filtration is not a new technology but is quickly gaining popularity in the automotive segment. With the ability to filter down as small as a paper filter element with the ability to be washed and reused!

The K&P Engineering filter element is made from medical grade, type 304 stainless steel micronic filter cloth to provide unmatched protection against oil contamination and resultant engine damage. A one inch square of this material flows an incredible 1.9 gallons of oil per minute at only 1 PSI pump pressure. The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above normal engine operating temperatures. A super strength nickel-plated neodymium rare earth magnet is installed in the top of the element for magnetic pre-filtering of the oil. The sophisticated bypass is engineered for proper differential pressures and consistent operation, delivering a greater percentage of filtered oil while being very easy to clean. The twist lock design assures positive filter element placement and allows for easy disassembly, inspection, and cleaning. The quad-ring gasket doubles the seal between the filter and the engine. Finally, the filter housing is carved out of solid 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat.

K&P Engineering manufactures stainless steel filters for a vast array of engines around the world. Staying at the forefront of design and testing allows this company to offer a top-tier product for your European vehicle.

Features:

  • Consistent filtering across entire filter surface
  • Superior ASTMF316 filtration performance
  • Magnetic Prefiltering
  • Progressive rate bypass combined with high flow characteristics of the filter media avoids unfiltered oil bypassing the filter during cold startup and high rpm
  • Easy inspection of engine contamination
  • Proven in Motorsports, Military and Aerospace applications for years. Technology is FAA approved for use in aircraft. 

At regular oil changes, clean to K&P's specifications for continued used - a true lifetime filter.

Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter.  Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon".  The lines and cooler are pressurized, but oil does not flow through them.  Flowing oil means it is being cooled and not just acting as an external reservoir.

Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing.  This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.

Features:

  • -8AN o-ring ports to provide a leak free fitting without the use of Teflon tape or sealant used by other oil cooler caps.
  • Viton o-rings are used throughout to maintain function and sealing in a high-temperature oil environment.
  • Use of the stock filter cap bolt to reduce cost and simplify installation.
  • An internal sealing mechanism to direct oil flow through the oil cooler and through the filter.
  • 1/8" NPT side port for external oil pressure gauge.

Kit Includes:

  • Oil filter cap with fittings
  • Oil filter sealing ring
  • BMW MANN Oil Filter and gasket

​Turner Motorsport Power Pulleys 
Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3. Race pulleys deliver even more power. 

Another "no-downside" upgrade, we even include a new belt. Total install time for a 3-piece pulley set should be around 1.5 hours. We offer three options in pulleys:
1.) No alternator pulley included - for cars with big amps and powerful stereo systems that need the extra juice.
2.) Street Power Pulleys - our most popular option with no downside!
3.) Race Power Pulleys - delivering 15 "free" horsepower, this set underdrives the water pump, power steering pulley, and alternator for lower temps, less wear, and more power. Not for street use. 

 

 

Intake Air Temperature Relocation Kit
Looking to maximize your power gains? Add a Turner IAT Relocation to combat power-robbing heat soak - the only true plug-and-play solution available. Heat soak is a real plague on consistent power for a stock or tuned vehicle. Click here to read more about our IAT relocation kit.

2001-2/2003 E46 330i/Ci, 2001-05 330Xi Stage 1 Performance Package
Peak Power Gain: +8hp / +10ft-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.

2001-2/2003 E46 330i/Ci, 2001-05 330Xi Stage 1 Engine Upgrade Kit includes:
aFe Cold Air Intake (oiled cotton filter, heat shield, intake tube)
Shark Injector performance software

Applications:
2001-2/2003 E46 330i sedan, 330Ci coupe and convertible (check your driver's door pillar for production date data)

As the producer of one of the finest working supercharger systems for the BMW E46 M3, Active Autowerke is proud to introduce the PRIMA PLUS supercharger system capable of exceeding 500 WHP running on pump drawn 93 octane. The PRIMA PLUS is an upgrade kit to the existing PRIMA supercharger system designed to create MORE horsepower.

A first in the BMW forced induction industry. For easy comparisons, here is where the PRIMA and PRIMA PLUS + stands when measuring rear wheel horsepower. A stock BMW E46 M3 is around 265 WHP. | PRIMA SC makes 425 WHP. | PRIMA PLUS SC makes 500+ WHP.

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.
