Forge Recirculating Valve for BMW N20 2.0 Turbo

Upgrade your BMW N20 2.0 turbo with the Forge Recirculating Valve, the proven diverter valve upgrade for reliability, boost holding and consistent performance. This high-quality, all aluminium, piston-based valve replaces the factory electronically controlled bypass valve that is known to fail when the rubber diaphragm splits, causing boost leaks and a loss of power. The Forge solution retains OEM ECU control while delivering the durability and boost stability enthusiasts demand.

If you have increased boost with an ECU remap, tune or software upgrade, or you drive in warmer climates, this is a must-have reliability upgrade. Even on a standard car it helps prevent the well-known diaphragm failure issue, which does not always trigger a check engine light and can quietly rob your BMW of performance.

Why choose the Forge Recirculating Valve for BMW N20

  • Direct OEM replacement for the electronically controlled bypass valve on BMW N20 2.0 turbo engines
  • Piston-based, all aluminium construction with no diaphragm to split or tear
  • Retains OEM ECU control of valve actuation for smooth drivability and correct fuelling
  • Improved boost holding and throttle response under hard acceleration
  • Ideal for tuned cars with increased boost and for stock vehicles seeking reliability
  • Helps prevent boost leaks, loss of power and inconsistent performance
