These valves are a direct replacement for the (OEM) original valves. They offer significantly higher flow rate capability, where other valves are just not up to it. This is achieved by utilizing 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 . This valve incorporates a unique conical, progressive rate spring that can allow for the retention of boost pressure up to 34 PSI. To ease installation there is a 360 degree adjustable vacuum hose connector .
