Forge Blow Off Valve

This Blow off valve has been designed as a direct replacement for the OEM valve on the Porsche 997 (Please purchase two valves). This valve is complete and ready to install with no fitting kit required. We supply the valve so that it is suitable for standard or mildly tuned engines. If your vehicle has been software tuned or running higher boost levels please contact us so that we can advise, on the required spring fitment.
