GFB DV+ EA888

The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So GFB’s DV+ solves this problem by replacing just the valve parts with an anodized billet aluminum housing fitted with a brass piston machined to exacting tolerances.

Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus either a different solenoid valve to actuate the pneumatic valve or a ballast resistor to plug into the OE wiring loom.  All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install.

Usually, the GFB T9351 DV+ is used on Audi/VW models, but because of the larger turbo used on the Mk7 Golf R and 8V S3 there is a distinct lack of space behind the diverter that prevents the T9351 from being fitted on these cars.

Sure, you could grind away some plastic and bend the intake pipe a little to make it fit, but that’s not really GFB’s idea of a “bolt-on” kit.  The T9359 solves this issue using a bespoke billet aluminium body that re-orients the solenoid to gain the clearance required for a perfect fit.  A 5 axis CNC machine is required to accommodate the larger size and extra complexity of this design, resulting in a true bolt-on solution that does not require any modifications to the car, and a fit that retains a factory-looking appearance.

Features:

• Retains the factory solenoid coil for seamless integration
• Replaces plastic valve parts with metal for reliability and strength on chipped engines
• Direct-fit replacement with GFB’s TMS benefits
• Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
