Forge Motorsport Billet Recirculation Valve Upgrade Kit

The Forge Motorsport FMDV27R is a premium performance upgrade engineered specifically for the Audi RS4 B9 and RS5 F5 platforms utilizing the 2.9-litre V6 TFSI twin-turbo engine. This comprehensive package features a pair of solenoid-operated valves alongside a custom-engineered wiring harness. The entire system integrates seamlessly with your vehicle's factory electronics, ensuring lightning-fast response times, optimal boost management, and absolutely no check engine lights, fault codes, or performance degradation.

Advanced Engineering Against Boost Leaks

The original factory solenoid valves utilize a delicate rubber diaphragm that is highly prone to rupturing, splitting, or fatiguing under increased boost pressure—especially on tuned or remapped vehicles. A ruptured diaphragm creates an immediate boost leak, causing diminished power delivery, sluggish throttle response, and excessive strain on your turbochargers. The Forge Motorsport engineering team solved this structural vulnerability by introducing a full aircraft-grade billet alloy construction combined with a highly durable internal piston-based design, delivering unrivaled longevity and reliability under extreme pressures.

Servicing and Custom Tuning Options

Unlike disposable factory units, this premium performance valve is completely serviceable and adjustable. It is engineered to deliver lightning-fast responses while operating quietly to mirror original equipment levels of refinement. For vehicles running aggressive ECU software or upgraded turbo configurations, the internal spring tension can be tailored to match your specific boost profiles. Routine maintenance ensures your intake architecture maintains a perfect seal for the lifetime of your performance vehicle.
