Forge Replacement Atmospheric Valve for BMW N20 2.0 Turbo
Upgrade your BMW N20 2.0 Turbo with the Forge atmospheric blow off valve, also known as a dump valve or diverter valve upgrade. This replacement valve is designed for N20 engines with the electronically controlled bypass valve, found in the F10, F20 and F30 chassis. Compatible models include 125i, 225i, 220i, 228i, 320i, 328i, 520i and 528i. Perfect for remapped and tuned cars where boost pressure is increased via ECU software, and ideal for unmodified vehicles operating in warmer climates.
If your factory rubber diaphragm has split or weakened, you can suffer a loss of boost pressure and power that may not trigger a check engine light. This Forge Motorsport BMW N20 blow off valve is a fully engineered solution that solves the common OEM diverter valve failure and keeps your turbocharged BMW performing at its best.
