Forge Motorsport Hard Pipe with Blow Off Valve - BMW N54 335i (FMBM335DV1-BLA-BLU-63)

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

Suitable for the BMW 335 fitted with the N54 Twin Turbo engine. This alloy hard pipe fits to the throttle body and incorporates our high flow blow off valve. This valve, fresh from our R&D department, is the largest displacement valve that Forge have ever made! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet!

The piston uses heat stabilised viton o-rings and high temperature grease to ensure a long life with minimal wear and very long service intervals.
