BMW Engine Oil Filter Housing Cap BMW 11427525334 X6 X5 328i 528i X3 N52 Engine

Description

The Genuine BMW Engine Oil Filter Housing Cap (OEM Part # 11427525334) is a structural composite cover designed to seal the top of the oil filter housing on BMW vehicles powered by N51, N52, N54, and N55 3.0L naturally aspirated and turbocharged 6-cylinder engines.

Constructed from heavy-duty, heat-resistant composite material, this cap houses the internal center stem cage and bypass relief valve that secure the oil filter cartridge. Replacing a cracked, cross-threaded, or worn cap prevents catastrophic engine oil leaks, oil pressure loss, and premature filter collapse.
