Like our full replacement atmospheric valve option, this valve is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which results in a boost leak. The later revsion OEM piston valves have a longer life but ultimately the plastic brittles and in extreme circumstances, parts of the plastic can break off. Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning fast response. It has also been proven in cars running over 600bhp !
This new valve has a very short overall installed height, which enables fitment of this recirculating valve into the tight space between the turbo and the inlet hose from the airfilter, older larger valves and sandwich plates will not fit this engine. Please be aware that the installation of this product is labor intensive
