GFB DV+ Diverter Valve BMW 1/3/4 Series (F20/F30/F32) / Alfa Romeo Giulietta/MiTo/Giulia / Fiat 124 Spider

GFB DV+ Diverter Valve BMW 1 Series, 3 Series, 4 Series/Alfa Romeo/Fiat 124 Spider

GFB is an Australian company well known for engineering smarter fixes to weak factory turbo hardware rather than just replacing it outright. The GFB DV+ keeps the factory solenoid coil, which is faster reacting than any aftermarket pneumatic valve, and pairs it with a billet aluminium housing and brass piston using GFB's pilot-actuated design for sharper, more reliable valve control under boost.

This listing covers a wide range of turbocharged BMW models built on N55 and N13 engines, including the 1 Series, 3 Series, 4 Series, X1, X3, X5 and X6 variants, along with Alfa Romeo Giulietta, MiTo, Giulia Quadrifoglio, Fiat/Abarth 124 Spider, and Jeep Renegade MultiAir applications. Check the tabs above for your exact model and year.

Note: The Alfa Romeo Giulia Quadrifoglio 2.9 requires two DV+ units per vehicle.
