High-Performance Blow Off Valve – Fits BMW N20 2.0L Turbo by Forge Motorsport

Description

Recommended Maintenance: We advise servicing this valve every 3 years or 20,000 miles, whichever comes first, to maintain peak performance.

Upgrade your BMW’s performance and reliability with this Forge Motorsport Blow Off Valve, specifically designed for BMW N20 2.0L Turbo engines equipped with the electronic bypass valve. This engine is found across various F-series BMW models, including:

• F10, F20, F30 chassis

• Models: 125i, 220i, 225i, 228i, 320i, 328i, 520i, 528i

This blow off valve is a recommended upgrade for:

• Vehicles with increased boost pressure via ECU software tuning

• Stock vehicles operating in warmer climates

Many BMW N20 engines are known to suffer from failure of the OEM rubber diaphragm in the stock bypass valve, leading to boost pressure loss—often without triggering a check engine light. This can cause a drop in power without the driver realizing it.

Why Choose Forge Motorsport?

Our solution is a fully engineered, piston-based valve with an all-aluminum construction, eliminating the risk of diaphragm failure. This valve:

• Offers significantly improved durability

• Retains OEM-level ECU control over valve operation

• Operates via pressure and vacuum, replacing the factory unit seamlessly

⚠️ Note: This valve is not compatible with BMW engines labeled B38, B48, or B58.
