GReddy Black Type-FV2 Blow-Off Valve

11501673 - "Black Out" - FV2 BOV The GReddy BOV Type FV was a new generation of blow off valve.  Now the Type FV 2 offer more improvements.  The unique "Floating Valve" design 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 pre-load 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 2 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.
