The GFB DV+ 9357 is a replacement solution for the original boost pressure valve in BMW N20 and N55 turbocharged engines. The valve improves boost pressure control, reduces pressure loss during gear changes and makes throttle response smoother, while maintaining the car's original control logic.

DV+ still utilizes the car's own electric solenoid, but replaces the factory valve's plastic internals with a metal structure. This improves the valve's tightness and reliability, especially at higher boost pressures.

Installation takes place directly in place of the original valve without software changes or permanent modifications to the vehicle.
