Why Upgrade?

The factory plastic valve covers found on many BMW N55 and S55 engines are a common failure point due to continuous heat cycles and engine vibrations. Over time, this can lead to oil leaks, PCV-related issues, boost leaks, and costly repairs. Our aluminum valve cover provides a stronger, more durable solution designed to handle the demands of both street and track use.

Installation Note

A gasket and hardware are included. However, for the best seal and leak-free performance, we strongly recommend installing a Genuine BMW OEM valve cover gasket during installation.

Warranty

This product includes a 30-Day Manufacturer Warranty against manufacturing defects in materials and workmanship.
