These valves are CNC machined 6061 aluminum which have been precision engineered to fit with the stock or aftermarket F-Hose and intake return hoses. The internal construction of the valve uses a machined piston with proper o-rings to ensure a smooth motion that is air tight to prevent any boost leaks. The spring has been engineered to hold moderate to aggressive boost increases on the 996TT vehicles. The valves feature a 90 degree removable swivel connection for easy fitting with the factory vacuum hose. If needed, the top of the valve unscrews allowing you to re-greased and service the valve. Valves are available in a polished finish and feature the Agency Power text and logo laser engraved on the top. As tested, these valves are a great upgrade for stock K16 or K24 cars and have even been used in our 700HP turbo kits.
