Upgrade your BMW N20 2.0 Turbo with the Forge Replacement Atmospheric Valve, the proven solution for reliability, performance, and that sought-after turbo whoosh. This atmospheric blow off valve, also known as a dump valve or diverter valve upgrade, is designed for BMWs equipped with the electronically controlled bypass valve, delivering stronger boost control and outstanding durability compared to the factory diaphragm unit.
Why choose the Forge Atmospheric Valve for BMW N20
- All aluminium construction for strength and heat resistance
- Piston based design with no rubber diaphragm to split or fail
- Direct replacement that retains OEM ECU control of valve actuation
- Ideal for ECU software tuned cars running increased boost
- Excellent reliability for unmodified cars in warmer climates
- Distinctive atmospheric sound on lift-off that enthusiasts love
Many N20 owners experience boost loss from the original rubber diaphragm splitting. This can happen without triggering a check engine light, leaving you down on power without knowing why. The Forge piston valve eliminates that weak point, helping to maintain consistent boost pressure and dependable performance on both standard and remapped cars.
