The GReddy Blow Off Valve FV features a unique "Floating Valve" design that incorporates a revised adjustable dual spring system, while maintaining the advantages of the previous models' push valve structure and silicone diaphragm control. The improved design makes spring preload setting less dependent on the idle, while providing increased response, valve travel, flow and resistance to premature valve lift under all conditions. The GReddy FV adopts the same mounting, outlet size and position as previous GReddy RS and RZ models, so retro-fitting to existing applications is possible. 100% genuine Part# 11531207 / BFV-311. GReddy product. Made by GReddy / TRUST Japan.
Fits 2001-2007 Mitsubishi Lancer Evolution 7-9 CT9A 4G63T
