Description
Enhance the durability and performance of your BMW’s turbo system with the Forge Motorsport Recirculating Valve, precision-designed for vehicles powered by the N20 2.0L turbocharged engine. This high-quality piston-type blow-off valve replaces the factory electronic bypass valve, which is known to suffer from failures due to a rubber diaphragm that can split over time—especially in high-boost or hot climate conditions.
The OEM valve’s diaphragm can fail without triggering a check engine light, causing unnoticed power loss and inefficient turbo operation. This is especially problematic in tuned vehicles with increased boost pressure or those operating under elevated temperatures.
Forge Motorsport offers a robust, performance-proven solution. Constructed entirely from aircraft-grade aluminum, this recirculating valve features a serviceable piston-based design—completely eliminating the weak factory diaphragm. It ensures consistent boost retention and responsiveness, while maintaining full compatibility with the BMW ECU’s electronic control for seamless integration.
Ideal for both modified and unmodified vehicles, this valve is a must-have upgrade for any N20-powered BMW seeking long-term reliability and enhanced turbo efficiency.
Recommended Maintenance:
Service every 3 years or 20,000 miles, whichever comes first, for optimal performance.
