The GFB DV+ T9396 is a complete replacement diverter valve for MultiAir turbo engines whose factory valve cannot be taken apart, built around a low profile integrated solenoid and supplied with a plug and play adaptor loom so the factory ECU keeps control of when it vents. GFB measured the OEM valve leaking 28 L/min at 1 bar of boost, the largest OEM diverter leak the company has recorded; 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, which sharpens throttle response and speeds boost recovery after a lift or a gearshift. It recirculates rather than venting to atmosphere, so it stays quiet and keeps metered air in the intake tract.
