Forge Motorsport Recirculating Valve for BMW N20 2.0 Turbo
Upgrade the weak factory diverter valve on your BMW N20 2.0 turbo with the Forge Motorsport recirculating valve for sharper throttle response, stronger and more consistent boost, and rock solid reliability. Also searched as a BMW N20 blow off valve, dump valve, recirc valve or turbo diverter valve, this is a direct replacement for the electronically controlled bypass valve fitted to the N20 engine in the F10, F20 and F30 chassis.
Fix the common N20 diverter valve failure
The OEM rubber diaphragm is known to split, causing boost leaks, loss of power and inconsistent performance. This failure does not always trigger a check engine light, so you can be losing boost without realising it. The Forge Motorsport piston valve removes the diaphragm entirely. It is an all aluminium, piston-based design that delivers significantly improved reliability on standard cars and remapped cars alike, especially in warmer climates.
Why choose this BMW N20 recirculation valve
- All aluminium construction with a durable piston design. No diaphragm to split.
- Retains OEM ECU control of valve actuation for smooth drivability and correct fueling.
- Direct replacement for the stock electronically controlled bypass valve.
- Helps prevent compressor surge and turbo flutter during gear changes and lift-off.
- Ideal for remapped, tuned or Stage 1 and Stage 2 N20 cars where boost pressure is increased.
- Restores and maintains consistent boost and throttle response on stock cars.
