The FTP Motorsport N54 Upgraded PCV Valve is an direct replacement for N54-powered models such as the E8x 135i and E9x 335i. It is highly recommended for high-performance or higher-mileage N54 engines to help prevent boost leakage, reduce oil consumption, and maintain optimal engine efficiency. FTP’s updated valve design (as of 06/2019) is unique to their product range and offers superior quality and durability compared to the cheaper alternatives commonly found online.

The factory plastic PCV valve on the N54 engine is known for poor pressure retention, even when new. Under boost, this can allow pressurised air to leak back into the crankcase, leading to increased crankcase pressure, oil consumption, and potential drivability issues. If the valve cover or gasket is worn, cracked, or loose, these problems are often amplified through internal or external pressure leaks.

Upgrading the PCV valve is an essential step in restoring proper crankcase control and ensuring the system can withstand the demands of a turbocharged engine.

The FTP Motorsport PCV Valve addresses these weaknesses with a solid aluminium construction and precisely machined internal components designed to fit tighter and last significantly longer than standard replacements. While no PCV valve is permanent, this upgraded unit greatly reduces common N54 PCV-related issues and is strongly recommended for tuned, high-boost, or high-mileage engines.
