Compatible with BMW M54 engines in E46s.

During spirited driving and on-track conditions, oil moves throughout the sump, causing oil starvation and premature, sometimes sudden, engine failure. This happens as the oil inside of the sump is sloshed around during high-speed cornering, acceleration, or braking. The movement of oil within the sump leads to oil starvation as the oil pump cannot pick up enough oil to properly lubricate engine components.

The primary purpose of the 5150 AutoSport Sump Baffle is to control the movement of oil within the sump, preventing oil starvation by creating compartments within the oil pan that prevent oil from pooling to one side under these driving conditions. By controlling the flow of oil within the oil pan, the baffle ensures that the oil pump pickup always has a steady supply of oil.

With consistent oil supply, critical engine components remain properly lubricated, preventing premature wear, overheating, and finally engine failure. Engines can continue to perform optimally, even under demanding conditions.

The 5150 AutoSport Sump Baffle requires the removal and modification of the sump, including baffle weld-in installation.
