All new from GFB. The DV+ is the most essential upgrade you need for your Fiesta ST. Ensuring that you don't loose any boost through the weak electrical standard valve, GFB replaces the weak, brittle plastic with precision engineered components that will outlive the life of your car. By ensuring the standard valve never fails, you will be able to run more boost and run the boost earlier.
 
GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles.
 
The Solenoid Coil itself from the factory-fitted valve is great as the ECU opens it faster than any Pneumatic Valve, so why replace it? The weak point however is the Valve Mechanism itself. GFB’s DV+ solves this problem by replacing the valve parts with an Anodised Billet Aluminium housing, fitted with a Brass Piston machined to exacting tolerances.
The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it.
