The Forge Supersize valve has been specifically designed and engineered to offer extreme flow rate capability, where only the largest valve will do. Often when engines have been tuned by installing larger turbo's , software upgrades, and many other boost increasing modifications, improved turbo response can be achieved by fitting the Forge Supersize valve which has the advantage of a greater internal mass air flow specification utilising an amazing 50mm (2") internal bore and an aerodynamic piston to direct the air through the large 40mm inlet and discharge ports (1 5/8"). Available in machined alloy finish. PLEASE NOTE : Where the standard valve fitted to your car was electronic (solenoid operated) the solenoid cannot be disconnected without causing a check engine light. This valve is designed to replace existing vacuum operated valves.
**Designed for custom big turbo applications, we do not have a install kit for this product.
