GFB DV+ T9366 diverter valve Alfa Romeo Giulia/ Stelvio, BMW X5/X6 M (GFBDVT9366)

The original valves already leak at higher boost pressure straight from the factory, which causes a loss of power that is even more pronounced on tuned vehicles because of the higher boost pressure. The DV+ therefore protects the turbocharger and improves response. Installing the GFB DV+ closes this “hole” in the charge-air system, and the vehicle has noticeably more power and torque. This has been demonstrably tested on the dyno! Advantages: - 100% sealed even at high boost pressures (flawless up to 2.5 bar) - noticeably more power and torque - made of aluminium (housing) and brass (piston): more reliability and durability on tuned vehicles - Faster boost build-up compared with an original diverter valve - Plug & play: easy installation within 10-15 minutes, as the original control unit is retained. This valve can only be used in combination with the original solenoid valve unit. The following picture shows the installation position of the DV+ together with the control unit of the original solenoid valve:
