Forge Motorsport E-DV Recirculating Valve for Renault Megane MK4 RS & Alpine A110
This Forge Motorsport E-DV is a direct-fit electronic recirculating diverter valve for Renault’s 1.8 TCe turbo petrol engine used in the Megane MK4 RS and Alpine A110. It replaces the factory electronic diverter on the turbo housing to improve boost control and reliability while keeping a near-stock sound.
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 recirculating design routes air back into the intake, so it is quieter than an atmospheric valve and better suited to a subtle, OEM-like feel.
Expect smoother throttle transitions and more consistent boost. This part will not add big power on its own, but it supports tuned setups by holding boost more reliably.
Key benefits
- Direct plug-and-play with the factory electrical connector – no vacuum lines or extra modules.
- Fast response for crisper throttle and smoother gear changes.
- Improved sealing to hold boost reliably, including on tuned cars.
- Quiet recirculating operation – near-stock sound with only a subtle whoosh.
- CNC billet aluminium body with an integrated electronic pilot valve.
- Serviceable design for long-term reliability.
- Helps reduce compressor surge (the chattering you hear on lift-off) for smoother turbo operation.
- Works with the stock ECU control strategy – no remap required.
