Forge Motorsport Replacement Atmospheric Valve for the BMW N20 2.0 Petrol Turbo Engines

Forge Motorsport Replacement Atmospheric Valve for the BMW N20 2.0 Petrol Turbo Engines

This Blow Off, or Dump valve, is for the BMW N20 2.0 Turbo engines that have the electronically controlled bypass valve. This engine can be found in the F10, F20 and F30 chassis badged as 125i, 225i, 220i, 228i, 320i, 328i, 520i and 528i. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.
