GFB T9659 DVX - Upgrade Recirc / Blow Off Valve - Audi S3 8V

Increased boost holding and throttle response with total volume control!

GFB’s DVX range takes the extremely popular DV+ Diverter Valve performance and fit, then adds our patented Venting Bias Adjustment Systems from the Respons range of valves. This feature allows you to infinitely vary how much air is recirculated, and how much is vented to atmosphere, giving you total control over your blow-off sound – completely adjustable from silent to ear shattering!

The DVX is not just a showy noise maker either. Using GFB’s proven TMS Technology, whilst retaining ECU control, the DVX solves all the performance and reliability issues that are common with factory diverters AND gives you a blow-off sound that’s completely adjustable!
