Advanced engine protection meets lifetime durability. Upgrade your brittle plastic housing to precision-engineered aluminum.
The factory plastic oil filter cap on BMW engines is a notorious weak point; it becomes brittle over time, is prone to leaking, and requires a specialized tool to remove. The Bevinsee Billet Aluminum Oil Filter Cap is the ultimate upgrade for your N54, N55, or S55 engine. Not only does it provide a permanent, leak-free solution, but it also introduces an innovative layer of engine protection with its integrated high-power magnet.
Why This is the Ultimate Oil System Upgrade:
- Innovative Magnetic Protection: Tiny metal particles are a natural byproduct of engine wear. Our cap features a built-in magnet with a large surface area to trap these metallic contaminants before they can circulate back through your engine, extending the life of your S55, N55, or N54.
-
No Special Tools Required: Forget the expensive BMW oil filter wrenches. This cap features a 21mm hexagonal head, allowing you to perform oil changes with a standard socket or wrench.
-
Billet Aluminum Strength: CNC-machined from premium 6061-T6 billet aluminum. It will never crack, warp, or strip like the OEM plastic part (replaces OEM #11427525334 & #11427566133).
-
Anodized for Longevity: The surface is anodized for superior rust and corrosion resistance, ensuring it stays looking new even after years of oil changes.
Installation & Maintenance Notes:
-
Reuse the Cage: After removing your old plastic cap, you must transfer the center plastic "cage" to your new aluminum cap.
-
Replace O-Rings: Always use a fresh rubber O-ring (included) during installation to ensure a perfect seal.
-
Wrench Ready: Use a 21mm socket for easy, low-torque installation.
