Forge Type RS Valve - Atmospheric
The Forge RS valve has been specifically designed and engineered, to offer extreme flow rate capability, where other valves are just not up to it.
Often when engines have been tuned by installing larger turbos or even software upgrades improved turbo response can be acheived by fitting the RS valve which has the greater internal mass air flow specification utilising an amazing 50mm (2") bore. For fine tuning there is a variable spring preload incorporated and a ratchet type top adjuster that will allow for the positive and precise adjustment that your driving style demands.
To ease installation a 360 degree adjustable vacuum hose connector With a choice of inlet and outlet connections the RS valve can be matched to your engine perfectly.
