GFB Respons TMS T9025 Adjustable Bias Venting Diverter / Blow-Off Valve (25 mm)
Adjustable Diverter / Blow-Off Valve With Venting Control
The GFB Respons TMS T9025 takes traditional diverter and blow-off valve functionality further by allowing you to precisely adjust the balance between recirculating intake air and venting it to atmosphere.
Customisable Sound Without Compromise
By twisting the adjustment ring, you control how much air vents to atmosphere versus recirculates back into your intake. This means you can enjoy a more pronounced blow-off sound or keep things quiet — all while maintaining driveability on sensitive turbo systems.
Sharper Response and Boost Management
The unique GFB TMS operating method supports faster boost recovery and improved throttle response, helping your turbo system return to peak pressure more quickly after upshifts.
Engineered for Fitment and Reliability
The T9025 is supplied as a bolt-on replacement where applicable, using the correct 25 mm inlet and outlet size. Its robust construction and venting bias system make it suitable for a range of turbo cars without causing common issues associated with fixed-venting BOVs.
