GFB DV+ T9302 Recirculating Bypass Valve for Select 1997-2021 Audi, VW, Porsche, and Polaris (1.8T / 2.3T)

Fits select 1997-2021 Audi, VW, Porsche, Saab, and Polaris RZR models (1.8T / 2.3T).

The factory diverter valve on many turbocharged Audi, VW, and Polaris models is a frequent failure point. Constructed from plastic with a rubber diaphragm, these OE units are prone to rupturing, leading to significant boost leaks and power loss. Furthermore, their "normally open" design often compromises part-throttle boost response. The GFB DV+ (T9302) is a precision-engineered solution designed to replace vulnerable factory internals with high-strength, performance-oriented components.

The DV+ utilizes a balanced piston design and CNC-machined metal construction to ensure permanent reliability under extreme boost pressures and temperatures. Unlike the factory valve, the GFB unit maintains a more efficient seal, providing sharper throttle response and ensuring your turbo system holds target boost levels consistently.

• Direct bolt-on replacement for factory plastic/rubber diverter valves
• CNC-machined metal construction ensures reliability under extreme conditions
• Adjustable spring pre-load for optimum throttle response and tuning
• Balanced piston design prevents premature venting or boost leaks
• Manufacturer Part Number: T9302
