Don't waste 0+ on a "Brand Name" version of this blow off valve when you can buy an
identical one
without their "Sticker Horsepower" for 4X Less Money!
The FV is a new generation of blow off valve.  The unique "Floating Valve" design incorporates a revised adjustable dual spring system, which improves performance via a push valve structure and silicone diaphragm.  The improved design makes spring pre-load 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 which draw in surrounding air to amplify the blow-off sound.  The BOV FV adopts the same mounting and outlet size and position as previous RZ and RS blow off valve models, making retro-fits onto existing applications incredibly easy.  Each valve can support up to 430HP!
Each valve kit comes with a custom flange adapter making it a direct bolt-on for 02-05 WRX 2.0L (EJ205), 06-07 WRX 2.5L (EJ255) and 04-19 WRX STI 2.5L (EJ257) Engines!
