A diverter valve uses vacuum actuation to re-circulate excess boost pressure into the turbo inlet pipe, allowing for quicker boost recovery. If the inner diaphragm is cracked or torn, boost pressure is lost and performance is compromised. Genuine kayser diverter valve sourced from Porsche ag in Germany to ensure quality, reliability and precise fitment. We recommend upgraded diverter valves for modified cars running more than .7 bar (10.29 psi). Please purchase part # fvd123212 if you have a modified car. Sold individually.
