Forge Atmospheric Blow Off Valve Kit

Introducing the Forge Atmospheric Blow Off Valve Kit, a superior alternative to your vehicle's standard dump valve.

Our high-performance blow off valves are meticulously designed to withstand increased boost pressures and outperform OEM counterparts. They offer two options for car enthusiasts: the recirculating valve, which discreetly returns excess air to the intake system, or the atmospheric valve, which releases pressure into the atmosphere, producing a distinctive whoosh sound.

The stock dump valves fitted on most vehicles, often with a soft diaphragm, tend to wear out over time and may cause performance issues. Forge Motorsport's blow off valves prevent such failures by providing efficient pressure release and ensuring quick boost recovery when you return to the throttle.

For some vehicles, Forge offers a choice between recirculating dump valves and atmospheric dump valves. The former is typically found on factory-fitted systems, silently recirculating excess air back into the inlet. Meanwhile, the latter vents pressure to atmosphere, producing the classic blow-off sound associated with turbocharged engines.

Please double-check the title to ascertain which type of valve is being supplied. Atmospheric valves are not compatible with all vehicles due to potential engine compatibility issues. Recirculating valves, on the other hand, do not produce the audible "blow-off" noise but will work seamlessly with increased boost pressure levels.

For selected cars where the dump valve is connected to the ECU, Forge provides a comprehensive kit that includes all necessary wiring and plugs. All products come with clear installation instructions for hassle-free fitting.
