Forge Atmospheric Race Blow Off Valve Subaru Forester XT 2004-2007

Regular price $175.50


The Forge blow off valve is made from billet aluminum, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound most commonly associated with rally cars when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

Dual-Piston Atmospheric Valves and Valve Fitting Kits - All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. .

While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Note: Please allow Forge Motorsports' orders up to two business days to ship out.
