GFB Universal Respons Blow Off Valve - Universal 33mm Inlet 33mm Outlet

The GFB Respons Blow Off Valve features a quick and easy bias adjustment system, to ensure valve noise output can be changed depending on the situation.The blow off/dump valves vent unused boost pressure when the throttle pedal is released, maintaining turbo performance, optimising response and minimising lag. The Respons Blow Off Valves provide a facility to adjust the vented noise from silent through to full atmospheric with a simple twist of the cap ring, and includes a 'lock out' facility to recirculate all dumped gas where legal requirements specify this. The Respons TMS is available in either application specific or universal fitments, and it particularly useful for installing in set ups where air meters are sensitive to fluctuations (such as VAG systems) due to the ability to adjust accurately.
