GReddy (11501665) Blow-Off Valve;

Greddy has updated their popular blow off valve for late 2013 with a new Type FV series universal BOV. The GReddy BOV FV is a new generation of blow off valve. The unique "Floating Valve" design incorporates a revised adjustable dual spring system, while maintaining the advantages of the previous model's push valve structure and silicone diaphragm control. The improved design makes spring preload setting less dependent on the idle, while providing better response, increased valve travel, more air-flow and added resistance to premature valve lift under all conditions. Also maintained is a slimmer CNC outlet with discharge ports to draws surrounding air to amplify the blow-off sound, however this can be replaced with optional re-circulation adapters in various sizes. The BOV FV adopts the same mounting and outlet size and position as previous GReddy RZ and RS models, so retro-fitting onto existing applications is possible. All GReddy BOVs are compatible with standard GReddy Blow-off Valve flanges (flange NOT included).
