Billet alloy oil filter cap upgrade for BMW N-series engines
Replace the fragile factory plastic cap with a precision billet upgrade that delivers strength, reliability and peace of mind. This premium metal oil filter cover is a direct swap for the OE unit and is designed for cars running the N20, N52, N54, N55 and S55 powerplants. If you are chasing reliability on a tuned road car or a hard-driven track build, this is the service part that stops the common cracking and seepage issues that come with the stock plastic housing.
We run these on our own cars and our customers love the fit and finish. The solid construction shrugs off heat cycles and pressure, helps prevent oil leaks, and looks the part every time you open the bonnet. It is an easy, worthwhile reliability upgrade for your next oil change and a smart addition to any performance-focused maintenance plan.
Why choose this uprated filter cover
- Direct replacement for the OEM plastic cap to reduce the risk of cracks and oil loss
- Precision machined billet construction for durability under heat and pressure
