Through experimentation and data acquired from our E36 World Challenge Touring Cars, it was discovered that in long corners and under heavy braking that there was an oil starvation problem in the M50 and M52 engines. This system was developed to keep oil in the sump and eliminate the starvation problem. After several iterations, further testing and data acquisition in the Touring Cars showed that this system eliminates the problem of oil starvation. This is a less expensive alternative to replacing the stock oil pan with the factory BMW M3 Lightweight oil pan, while still achieving the similar results.

*Requires Professional Welding

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!
