25mm Adjustable Recirculation Dump Valve

Made from billet aluminium, this Adjustable diverter valve  vents back into the intake system, similar to the OEM process with increased reliability and rebound under heavy load. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably and turns heads! IT also allows adjustability to the preload, to set it up to work in harmony with your driving style and engine. They are adjustable in terms of how much boost is returning back, allow basic tweaking of your boost system. 

Our 25mm Adjustable valves will fit all Audi, VW, SEAT, Porsche and Skoda (VAG) 1.8T and 2.7 Bi-Turbo engines, as well as numerous other vehicles. Please see compatible vehicles above and below, or contact us if you are not sure if this valve is suitable for your application.
