GFB ATMO DV+ Diverter Valve T9451 for Audi & VW 2006-2020 (2.0T)

Fits select 2006-2020 Audi and Volkswagen models equipped with the 2.0T engine, including A3, A4, A5, A6, Q5, GTI, Jetta, Passat, and Tiguan.

The GFB ATMO DV+ (T9451) is a direct-replacement performance solution for the factory solenoid-actuated diverter valves found in VAG applications. Unlike standard recirculating valves, the ATMO version vents to the atmosphere (VTA) to provide the signature turbo blow-off sound while maintaining the mechanical reliability GFB is known for. It utilizes GFB’s Turbo Management System (TMS) technology, which can provide up to 30% faster boost recovery during gearshifts by keeping the piston closed until boost is actually required to be vented.

By retaining the factory solenoid, this kit ensures the ECU remains in full control of the valve operation, preventing the fault codes often associated with standalone blow-off valves. It replaces the weak plastic internal components of the OE valve with precision-machined hardware designed for high-boost durability and longevity.
