G Reddy "FV2" CT9A Dump Valve Made in Japan, genuine Greddy item"Plug & Play" kit for Mitsubishi Lancer Evo 9 CT9A Engine code : 4G63High manufacturing quality Fast response and top reliability Adjustable trigger pressure and 360° rotatable body Type : return Made from forged aluminium G Reddy part number : 11531213G Reddy FV2 Blow Off Valve Kit for Mitsubishi Lancer Evo 9 CT9A Specifications Introduced in 2021, this G Reddy dump valve is a direct evolution of the former G Reddy FV generation. Still made of forged aluminum and based on a dual piston conception, this new version features a revised design while ensuring 100% backward compatibility thanks to its perfectly identical flange and dimensions. A new manufacturing process ensures even more reliability, and brings two major innovations: The opening pressure of the G Reddy FV2 dump valve is now adjustable with a knob. The body of the dump valve can be rotated 360° to facilitate its installation in narrow engine bays. The new G Reddy FV2 blow off valve ensures both stable idling and an extremely quick opening and closing time, even at low boost pressures. These unique abilities guarantee the highest reliability for any type of use, all while optimizing the turbo spool (maintains the rotation speed during gear changes for an improved response time / anti-lag properties). This kit for Mitsubishi Lancer Evo 8/9 CT9A was developed and approved by G Reddy in Japan, and contains everything needed for a plug & play installation. It allows a return type installation (recirculates back into air intake).
