Forge Recirculating Valve for BMW N20 2.0 Turbo - the proven upgrade for reliability and boost control on BMW turbo petrol models. Also known as a BMW diverter valve, BMW dump valve or BMW blow off valve upgrade, this Forge piston-based valve directly replaces the factory electronically controlled bypass valve on the BMW N20 engine.
Common on N20 cars, the original rubber diaphragm can split and leak, especially on tuned cars running higher boost or vehicles used in warmer climates. That means lost boost and lost performance, often without a warning light. The Forge valve solves this with an all aluminium, diaphragm-free, piston design that resists failure and keeps your turbocharger performing consistently. It retains full OEM ECU control of valve actuation for smooth drivability and reliable operation.
