This BMW E46 billet aluminum oil filter cap from ECS Tuning replaces your original plastic filter cap, improving the look of your engine bay and solving the problem of a rounded removal lug, cracks and buggered threads. The cool thing is that the ECS unit features an OE 36 mm hex head as well as a 17 mm hex, the same size as the oil drain plug.

Stronger than plastic, the ECS oil filter cap uses the OE filter and filter housing O-ring. Black anodized to prevent oxidation, the ECS cap threads on just like the factory cap and is made in the U.S.A. $129.97 at time of publication.
