Product Description

Price is for one pair (one pair required per vehicle).

Our direct replacement diverter valves will eliminate the notorious Honking sound commonly heard when the OEM valves have failed. Our valves will restore lost power and will hold more boost pressure than the stock units for added performance. In addition, they recover quicker than the OEM valves which allows better spool up after shifts. We designed our valves with a 90 degree vacuum port which allows for additional vacuum line clearance and a trouble free installation. The EVO billet diverter valve for the 996TT / X50 / GT2 comes as a complete kit and carries our exclusive lifetime warranty.
