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!

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

This part fits the following BMWs
1992-1999 E36 323i 325i 325is 328i 328is

This new generation oil is made with a quality synthetic base and includes a molecular friction modifier for reduced friction and wear. It also glows under UV light so leaks can be easily traced! This unique oil contains a fluorescent green chemical friction modifier to smooth out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown a reduction in friction coefficient of as much as 15%! MolyGen oil is also a great choice for modern turbocharged engines which produce much more heat.

This is the replacement OEM oil filter kit for the S54 engine, as used in the E46 M3, Z4 M Roadster and M Coupe, as well as the 2001-2002 MZ3 M Roadster/Coupe (with S54 engine). This is the complete oil filter kit - filter, large o-ring for filter housing cover, small o-ring for bolt seal, flat washer for bolt, and copper seal ring for the drain bolt. It's everything you would need to complete an oil change - minus the Castrol 10W60 oil of course, which we sell at a great price. This kit is manufactured by Mahle - the original supplier to BMW for the 11427833769 BMW filter (factory filters come with the Mahle part number OX 187 printed on the cap).

Why Mahle over Mann? In the past we have sold a few different oil filters for the E46 M3 and S54 engines. But Mahle is the true OEM supplier for this part number. It fits perfectly and is the exact replacement part at nearly the same price as the slightly different Mann filter (and less than the factory BMW filter). For more detail, click here.

This filter fits the following BMWs:
2001-2006 E46 M3
2001-2002 MZ3 - M Roadster & M Coupe (S54)
2006-2008 MZ4 - M Roadster & M Coupe
