Forge Motorsport Blow Off Valve for Toyota Yaris GR Turbo
The Forge Motorsport Blow Off Valve is specifically designed for the Toyota Yaris GR Turbo engine with the electronically controlled bypass valve (OE Part no. 7.04654.08). This valve is recommended for vehicles that have undergone an ECU software upgrade to increase boost pressure, as well as for unmodified vehicles operating in warmer climates. It serves as a solution to the common failures that occur with the stock valve.
Unlike the stock valve, the Forge Motorsport Blow Off Valve is a fully engineered solution that offers improved reliability. It features a piston-based design, eliminating the need for a diaphragm that can fail. The valve is constructed from high-quality aluminum billet, ensuring durability and longevity. It replaces the original unit with a pressure/vacuum operated piston valve, while still retaining the desirable OEM ECU control over valve actuation.
The Forge Motorsport Blow Off Valve is available in two options: Atmospheric and Factory type. The Atmospheric valve produces a distinctive noise when the throttle is lifted, adding a sporty sound to your vehicle. The Factory type valve is non-noise recirculating, providing a quieter operation.
The package includes the FMDV34 Valve, 2.5m of 4mm Vacuum Tube, 4mm Brass T-piece, 3 port Solenoid and fixings, Cable Ties, Uprated Red Spring, Wiring loom, Forge USB Instructions, Forge Keyring, and Sticker. This comprehensive kit ensures easy installation and optimal performance.
If you want to further customize the valve to suit your engine’s needs, a spring tuning kit is available separately.
