Description
The MMX Performance Billet Oil Filter Housing Cap is the ideal replacement for the fragile plastic OEM housing found in many BMW engines. Replacing the factory cap with this billet aluminium upgrade solves the common problem of cracked housings and oil leaks during routine maintenance.
Each housing cap is precision-machined from aerospace-grade 6061 aluminium using advanced 5-axis CNC technology. After machining, the part is polished and finished in a Midnight Black gloss anodize for long-term corrosion resistance and a premium appearance. This design offers significantly increased strength and durability over the factory plastic component.
Installation is simple and best completed during an oil and filter change. The billet cap includes a factory-spec O-ring for a perfect seal and accepts the stock oil filter insert and internal components.
This cap is a direct fit replacement for BMW part number 11427525334, delivering both enhanced functionality and lasting aesthetics.
Please Note: Older images may show the previous Dark Anthracite finish. Prolonged exposure to extreme heat may slightly affect the anodized finish, but not the function or structural integrity of the cap.
