The Forge Type RS atmospheric piston valve has been specifically designed and engineered, to offer extreme flow rate capability, where other valves are just not up to it.

Improved turbo response can be acheived by fitting the Type RS valve which has the greater internal mass air flow specification utilising an amazing 50mm (2") bore.
