Forge Motorsport Recirculating Valve for BMW N20 2.0 Turbo
Upgrade the factory electronic bypass valve on your BMW N20 2.0 turbo petrol engine with this Forge Motorsport recirculating valve. This diverter valve is a proven reliability upgrade for F10, F20 and F30 chassis models including 125i, 225i, 220i, 228i, 320i, 328i, 520i and 528i. Perfect for cars with an ECU software upgrade and also for standard vehicles in warmer climates.
Why upgrade the N20 diverter valve
The original valve on the N20 uses a rubber diaphragm that is known to split. This creates a boost leak and results in a loss of performance. The failure does not always trigger a check engine light, because the valve can be pushed open by boost pressure. Many owners are unaware they are losing power.
Forge solution
Forge replaces the factory unit with a fully engineered, all aluminium, piston-based recirculating valve. There is no diaphragm to fail. The valve is operated by pressure and vacuum and it retains OEM ECU control of valve actuation for seamless integration with the car’s management system. The result is significantly improved reliability and consistent boost delivery, especially on remapped cars running increased boost pressure.
Key features
- Direct replacement for the N20 electronically controlled bypass valve
- Piston design with no diaphragm to split
- All aluminium construction for durability
- Retains OEM ECU control for smooth, factory-like operation
- Recommended for cars with ECU software upgrades and for vehicles used in warmer climates
- Helps prevent boost leaks and power loss caused by the stock valve
