GFB DV+ is a direct-replacement diverter valve upgrade for the BMW N20 turbo engine. It retains the factory solenoid and ECU control for plug-in installation while replacing the failure-prone factory plastic diaphragm with a metal piston, opening about 10% faster and closing about 50% faster than stock for sharper throttle response and reliable boost holding.
