Forge Motorsport Blow Off Valve for BMW N20 2.0 Turbo Engines
The Forge Motorsport Blow Off Valve is specifically designed for BMW N20 2.0 Turbo engines found in the F10, F20, and F30 chassis. This valve is compatible with various BMW models including 125i, 225i, 220i, 228i, 320i, 328i, 520i, and 528i. It is an ideal choice for vehicles that have undergone an ECU software upgrade to increase boost pressure, as well as unmodified vehicles operating in warmer climates.
One common issue with the original electronically controlled bypass valve is the failure of the rubber diaphragm, resulting in a loss of boost pressure. This failure may not trigger a check engine light, making it difficult to detect the power loss. To address this problem, Forge Motorsport offers a fully engineered solution with improved reliability.
The Forge Motorsport Blow Off Valve features a piston-based design, eliminating the need for a diaphragm that can fail. It is constructed entirely from aluminum, ensuring durability and longevity. This valve replaces the original unit and operates using a pressure/vacuum operated piston valve, while still retaining the OEM ECU control over valve actuation.
Please note that this blow off valve is not compatible with B38, B48, or B58 engines.
