Forge Motorsport E-DV Atmospheric Valve for Toyota GR Yaris/GR Corolla
This Forge E-DV Atmospheric valve is a direct-fit electronic blow off valve for the Toyota GR Yaris and GR Corolla 1.6 turbo G16E-GTS engine. It replaces the factory electronic diverter valve to give sharper boost control and a clear turbo whoosh on lift-off.
Why choose this valve
- Plug-and-play with the factory connector – no vacuum lines or extra parts.
- Quicker response for crisper throttle and smoother gear changes.
- Improved sealing to hold boost more reliably, especially on tuned cars.
- Atmospheric vent gives a noticeable turbo sound when you lift off.
- CNC billet aluminium body with an integrated electronic pilot valve.
- Serviceable design for long-term reliability.
- Helps reduce compressor surge for smoother turbo operation.
What it does
A diverter or blow off valve releases pressurised air when you lift off the throttle. This protects the turbo and helps keep it spinning, so the car gets back on boost faster when you press the pedal again. The Forge E-DV reacts quickly and holds boost securely. Expect better consistency and drivability rather than a big power gain on its own.
Fitment
Designed for Toyota GR models with the 1.6 3-cylinder turbo G16E-GTS engine, including:
Toyota GR Yaris and Toyota GR Corolla.
Use our vehicle lookup to confirm fitment for your car, or check the Vehicle Fitment tab for full details.
Important: For GR Yaris and GR Corolla only – not for standard Yaris, standard Corolla, or other Toyota engines.
Good to know
This is the Atmospheric version, so it vents to air for a louder sound. No ECU remap is required. It is a direct replacement for the OEM electronic valve on the turbo housing, using the factory control strategy. The unit is fully serviceable to maintain performance over time. If you prefer a near-stock sound, a recirculating version is available separately.
