- 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
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 (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 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. Read all about the DV+ story on the next page.
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.
GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/turbo flutter. Oh, and it doesn’t require different springs or frequent re-builds.
Is this the right valve for me?
If you haven’t already checked that your vehicle is on the fitment list, do that first using our vehicle search function above.
If you get a few different valve options for your vehicle, use the guide below to make sure you’re choosing the right one for your needs:

- Sharper throttle response
- Faster boost recovery on gearshift
- Solves boost leaking issues
- Built to last
European manufacturers are pushing their engines to the limit. Get a DV to match.
GFB's DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product.
GFB’s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” to ensure better performance on stock or modified engines.
Furthermore, these benefits won’t cost you the Earth! Rather than throwing the entire factory diverter valve system in the bin (like other manufacturer’s “solutions”), the DV+ keeps what works and replaces what doesn’t. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation.
