Known as the “Hybrid”, this world-first became the flagship model of the newly formed company Go Fast Bits. The two venting ports of this revolutionary valve were staged on the body such that the recirc port opened before the atmo port, helping to prevent backfiring and stalling on cars with a MAF sensor, whilst still giving the signature blow off sound when the car is driven harder.

On the surface, the GFB Respons BOV look like just another dual-port blow-off valve, but the GFB Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the GFB Respons allows you to precisely control how much air vents from each of the two outlets.
