Description
GFB DV+ T9357 retains the factory electronic solenoid and replaces the plastic valve mechanism with a machined-metal assembly for stronger boost control and sharper response. GFB lists selected BMW N20 applications, including specified 220i/228i, 320i/328i, 420i/428i, 520i/528i, X1, X3, X4 and Z4 models, plus the 2015-2021 BMW M2 F87 with N55B30T0 engine. Access to the factory diverter is extremely tight on some N20 vehicles and installation may require loosening the turbo manifold. Confirm the exact engine, chassis and year against GFB’s official list; this is not universal fit.
