Forge Motorsport Dual-Piston Atmospheric Valve
The Forge Motorsport Dual-Piston Atmospheric Valve is a high-performance upgrade for your vehicle’s forced induction system. Made from billet aluminium, this valve is designed to vent 100% of the residual charge air to the atmosphere when the throttle is lifted, creating the iconic “Whoosh” sound commonly heard in rally cars. Not only does this valve enhance the auditory experience, but it also improves throttle response and maintains boost pressure more reliably.
With a dual-piston design, this atmospheric valve ensures efficient and effective venting of the charge air. It comes with an uprated blue spring and an uprated red spring, allowing you to adjust the valve’s performance to suit your specific needs. The valve also includes a 28mm blanking plug and 40mm hose clamps for easy installation.
Please note that while Forge Motorsport has taken measures to ensure compatibility with mass air-flow sensor equipped vehicles, it cannot guarantee compatibility with all applications. It is essential to ensure that your vehicle’s engine management system can compensate for the loss of metered air through a vent-to-atmosphere valve.
