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!
