GReddy Type-FV 2 Blow-Off Valve

Sale price$340.00


The GReddy FV2 is the second iteration of our latest generation blow-off valves. The new and improved spring stiffness adjustment is now easily changeable by the use of our "detent" knob on the top of the unit. 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.  This original 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 FV, RZ and RS models, so retro-fitting onto existing applications is possible. All GReddy BOVs are compatible with standard GReddy Blow-off Valve flanges.
