This is a piston design bypass valve that is a direct replacement for the original fitment. This valve gives greater longevity than the diaphragm (OEM) valves but also benefits from its ability to be fitted with different springs when the boost pressure has been increased or the engine has been modified. 

* To avoid the possibility of a P0101 trouble code, the ECM must be reprogrammed with a tune optimised for atmospheric discharge. We recommend the tuning services of Trifecta Performance: www.trifectaperformance.com
