Forge Motorsport Diverter Valves

We carry a wide range of performance racing diverter valves for popular European vehicles. Our diverter valves are designed to replace the weak factory diaphragm units with a piston and spring design.  The aftermarket diverter valves help hold the boost consistant in the higher RPM's without leaking or bleeding boost off.  We carry diverter valves from Agency Power, Forge Motorsports, Hyperboost, GFB, AWE Tuning, APR Tuned, EVO, and much more.
