Go Fast Bits Fully Adjustable Sound BOV/Diverter GFB-T9035

If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.

• Patented Venting Bias Adjustment Sysem-Can be Infinitely Adjusted between Full Recirc (silent) and full atmosphere (loud). Change the venting bias simply by twisting the adjustment ring.
