With great looks and performance to back them up, the Mazdaspeed Protegé is a sport compact enthusiasts dream come true. Forge Motorsport have manufactured a valve that helps keep that dream in reality. The MSP01 is a unique twin piston blow-off valve that replaces the OEM piece. The 2 stage design allows the car to operate normally without worry of stalling, poor idle or check engine lights. Under boost the valve has a clean crisp sound that will definitely get you noticed. Aside from the head turning "Swoooooosh" the MSP01 looks as good as it sounds.
Machined from Billet aluminum the MSP01 is completely tunable and serviceable to keep up with your modifications as they progress. Installation is simple and takes less than 10 minutes. The MSP01 comes with Forge’s "No Hassle" limited warrantee and is available with your choice of two great finishes.
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.
Forge Motorsport nor any of it’s 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.
