The GFB Hybrid BOV returns as a celebration of one of the most influential blow-off valves ever created. Originally engineered with two staged venting ports—where the recirculation port opens before the atmospheric port—it delivered the perfect balance of drivability and sound. This breakthrough design prevented backfiring and stalling on MAF-equipped vehicles while still producing the aggressive blow-off tone enthusiasts love under harder acceleration.
Its success paved the way for future innovations like the Respons TMS and the electronically adjustable Deceptor Pro. Now, to mark 20 years since this game-changing technology reshaped the turbocharging world, GFB has revived the iconic Hybrid for a new generation of drivers.
