GFB DV+ T9381 Diverter Valve with Integrated Solenoid for Audi/VW/Porsche 2005-2020 (2.0T)

Fits select 2005-2020 Audi, Volkswagen, and Porsche models including A3, A4, A5, S3, GTI, Jetta, and Macan (2.0T).

The GFB DV+ T9381 provides a complete performance solution for factory-fitted electronic diverter valves. Unlike the T9351 which requires reusing the factory solenoid, the T9381 features its own low-profile integrated solenoid. This design allows for a total replacement of the OE valve, making it the ideal choice for vehicles with tight engine bay clearances, such as EA888 Gen 3 engines found in MQB platform vehicles with aftermarket intakes or IS38 turbo upgrades.

By replacing the prone-to-failure plastic factory components with a precision-machined brass piston and billet housing, the T9381 solves boost leaking issues and improves reliability under high-load conditions. The valve is engineered to remain shut until boost is requested to be vented, resulting in sharper throttle response and significantly faster boost recovery during gear shifts or brief throttle lifts.

• Improves boost holding and throttle response
• Faster boost recovery between gearshifts
• CNC machined billet aluminum and brass construction
• Direct bolt-on fitment to factory mounting points
• Manufacturer Part Number: T9381
