Aluminum Oil Filter Cap – BMW N20 N52 N53 N54 N55 S55 | OEM 11427525334

The original plastic oil filter cap on BMW N20, N52, N53, N54, N55, and S55 engines cracks, strips, or seizes over time — making oil changes difficult and causing leaks. This aluminum replacement cap is far more durable than the original plastic — machined to the same thread specifications with an integrated O-ring seal.

Fits OEM #11427525334.
