The GFB DV+ T9396-2 is a twin kit: two complete replacement diverter valves for the 2.9 litre twin turbo V6 in the Giulia and Stelvio Quadrifoglio, where each turbocharger needs its own valve. Each valve carries a low profile integrated solenoid and its own plug and play adaptor loom, so the factory ECU keeps control of when it vents and the air is recirculated rather than dumped to atmosphere. GFB measured the OEM valve leaking 28 L/min at 1 bar of boost; the DV+ holds pressure to 50 psi on a metal piston with a Viton face seal running in a piston seat machined into the valve body. Patented pilot actuation decouples the piston from the solenoid so the valve opens and closes progressively, sharpening throttle response and boost recovery. Fasteners differ by car: the Giulia uses E-Torx and the Stelvio uses regular Torx, and Stelvio access is from under the vehicle.
