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 individuals application will be compatible with a valve that vents the charge air into the atmosphere. Forge Motorsport nor any of its Authorised Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this. If you require your parts quickly then please check stock before ordering to avoid any unexpected lead time.
