GFB DV+ T9356 Diverter valve BMW N55B30 335i F30, M135i F20/F21.

Even ex works, the original valves leak at higher boost pressure, which causes a loss of power that is even more pronounced in performance-enhanced vehicles due to the higher boost pressure.

By installing the GFB DV+, this "hole" in the charge air system is closed and the vehicle has a noticeably better response and the turbocharger is protected.

Advantages:

- 100% tight even at high charge pressures (faultless up to 2.5 bar)

- Noticeably more power and torque

- Made of aluminium (housing) or brass (piston): more reliability and durability for performance-enhanced vehicle

- Faster boost pressure build-up compared to 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 conjunction with the original magnetic valve unit.
