Stock diverter valves just can't handle performance upgrades. Additional boost can extend the factory limits of operation and blow the diaphragm to pieces.

Forge Motorsports recognized this dilemma. They've engineered boost-hardy diverter and blow-off valves tough enough to take the pressure without blowing their lids.

These units utilize completely serviceable valves with an aluminum piston and o-ring seal - compared to the easily-torn rubber diaphragm found in the OEM valve.

The improved aluminum design and internal piston allow for faster response and improved durability.
