Forge Motorsport E-DV Recirculating Valve for BMW N20 2.0T
This direct-fit electronic recirculating diverter valve replaces the factory unit on BMW N20 2.0 turbo petrol engines. It improves boost control and reliability while keeping a near-stock sound.
What it does
A diverter valve (often called a blow off valve) releases pressurised air when you lift off the throttle. This protects the turbo and helps keep it spinning. The car then gets back on boost faster when you get back on the power. The recirculating design routes the air back into the intake, so it is quiet and OEM-like.
Expect smoother throttle transitions and consistent boost. This part will not add big power on its own, but it supports tuned cars by holding boost more reliably.
Why choose this E-DV
- Direct plug-and-play with the factory electrical connector – no extra wiring or vacuum lines.
- Fast response for crisper throttle and smoother gear changes.
- Improved sealing to hold boost, including on tuned setups.
- Quiet recirculating operation – subtle whoosh, near-stock sound.
- CNC billet aluminium body with an integrated electronic pilot valve.
- Serviceable design for long-term reliability.
- Helps reduce compressor surge (the chattering noise on lift-off) for smoother turbo operation.
- Works with the stock ECU control strategy – no remap required.
