GFB Respons TMS Direct fit Blow off valve or BOV with GFB TMS advantage T9007

All the performance with or without the noise!

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.

How GFB’s patented venting bias adjustment works

Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.

Complete Range of Fitment Options

The Respons direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments.
