The GFB DV+ (T9381) replaces the factory diverter valve entirely on VW and Audi TSI/TFSI engines that use a Pierburg diverter, rather than re-using the factory solenoid like the T9351. Its low-profile integrated solenoid allows fitment where clearance is tight, including the EA888 gen3 in the VW GLI, MQB platforms with an IS38 turbo or aftermarket intake, and the 4.0 TFSI. It improves throttle response and solves boost-leak and reliability issues.
