GFB DV+ T9357 diverter valve BMW 1–5 Series N20B20, M2 F87 N55B30, X models (GFBDVT9357)

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. Installing the GFB DV+ closes this “hole” in the charge-air system, and the vehicle has noticeably more power and torque. We have demonstrably tested this 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. Note for BMW N20 engines: fitting the valve is more difficult than on other models because of the tighter space. The exhaust manifold may have to be loosened slightly to make it possible to fit the DV+. 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:
