Forge Motorsport Ford Fiesta Mk8 ST & Puma ST Dump Valve

After huge demand, Forge have developed the perfect dump valve solution for the Fiesta ST MK8 and Ford Puma ST, two vehicles that Ford launched without an OEM valve included. As the engine does not have a diverter valve fitted as standard, Forge have developed a twin piston dump valve that not only gives you an incredibly loud sound when lifting off the throttle, but also increases the throttle response during gear changes by reducing turbo lag.
