Rocker Cover With Vent Valve & Gasket

Product Details

When you are chasing peak performance out of your turbo BMW, a cracked valve cover is a quick way to lose boost and introduce vacuum leaks. The factory N20 and N26 valve covers are notorious for hairline fractures and internal PCV diaphragm failures. Instead of paying dealership premiums for a box with a roundel on it, turn to Febi Bilstein for a high-quality, track-proven alternative that restores factory-level sealing and crankcase pressure regulation.

This Febi valve cover is engineered as a direct replacement for your worn or leaking factory unit. Made from high-grade, reinforced composite polymers, it features structural reinforcement to resist the intense heat cycling typical of modified, turbocharged engines. By replacing your cracked cover with this all-in-one assembly—which comes complete with fresh gaskets and new mounting hardware—you will eliminate oil pooling in your spark plug wells, fix rough-idle issues, and seal up your crankcase for consistent engine performance. Keep your engine bay clean and running strong with Febi.
