The GFB DV+ T9454 is a bolt-on solution designed to replace the original bypass valve in Ford Focus ST Mk.3 models and vehicles equipped with a BorgWarner turbocharger. The valve improves boost control and reduces boost loss during gear changes, while retaining the car's original ECU control logic.

The DV+ continues to use the car's existing electronic solenoid but replaces the factory valve's plastic internals with a metal construction. This improves the valve's sealing and reliability, especially at higher boost pressures.

Installation is direct to the original valve's location, requiring no software changes or permanent modifications to the vehicle.
