Forge Blow Off Valve 50mm


Forge Blow Off Valve 50mm

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

This valve is the largest displacement valve that Forge currently produce. The unique design features a 50mm (2”) aluminium piston (meaning no issues with split diaphragms). As we endeavour to continue our innovation, existing products are no exception. Therefore, we have now released the all new version of “FMDVRAY.” It has been difficult to improve upon this market leading design, but we have done just that. We run this valve on our very own Mk1 race car, that's how confident we are in the product!
