Oil pan baffle to prevent low oil pressure under long braking events for cars being road raced. Tested extensively under extreme conditions on our B46 race cars in many variants.
Generally fits later model B48D engines like on the G20 330i but we have seen engines come with either pan. The later model pan has a little bulge on the bottom of the pan next to the drain plug. If your pan does not have the bulge you would want the STROM 99.00038 baffle instead.
You can compare pictures of pans on Ebay.
