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 sound of your vehicle, but it also improves throttle response and maintains boost pressure more reliably.
With its dual-piston design, this atmospheric valve offers superior performance and durability. It comes with an uprated blue spring and an uprated red spring, allowing you to adjust the clamping load to suit your specific needs. The valve also includes two 40mm hose clamps and a Forge Motorsport sticker.
Please note that while the Dual-Piston Atmospheric Valve is designed to be compatible with mass air-flow sensor equipped vehicles, it may not be suitable for all applications. It is essential to ensure that your engine management system can compensate for the loss of metered air through a vent-to-atmosphere valve before installation.
