DV+ Performance Diverter Valve Range

GFB’s DV+ is the best performance solution for cars with factory-fitted electronic diverter valves. Using a patented pilot actuation system and precision CNC machined metal valve components, the DV+ design improves EVERY aspect of the factory diverter valve. Offering faster and more reliable operation, enhanced throttle response, boost holding, and longevity, the DV+ range is pound for pound, dollar for dollar, the best performance diverter solution on the market.

Better performance, unrivalled quality, and an affordable price point – this is what we mean by Performance Without Compromise.

Uncompromised throttle response for turbocharged engines

Modern OEM electronic diverter valves might be faster than pneumatic types, but they are binary in operation – open or shut. What they gain in operational speed, they lose in throttle response. The DV+ adapts the method of operation of the factory diverter system to give you the best of both worlds.

Pilot Operation – the patented design of the DV+ means the piston is not directly connected to the solenoid, so it can open and shut progressively. This operation method leads to improved throttle response and drivability, because the DV+ is more “discerning” about how much air it vents when triggered by the ECU – it only vents the amount of air necessary to eliminate pressure spikes that cause compressor surge, where the factory diverter opens fully whether it needs to or not.

When you close the throttle during spirited driving, the DV+ opens to prevent compressor surge and protect the turbo. When the pressure has dropped sufficiently, the piston begins closing to preserve a small amount of boost in the intercooler for as long as possible. This helps the turbo return to peak boost faster when you re-open the throttle. We call this the Turbo Management System (TMS) benefit.

Lightning-fast operation – vehicle manufacturers use an electronic diverter valve because they respond faster than pneumatic valves. Well, the DV+ is faster again! No other valve on the market comes close to matching the DV+ opening and closing speeds.

Hold my boost and watch this…

Your turbo works hard to create boost, so why make it work harder than it needs to? A GFB DV+ ensures that all your hard-earned boost makes it to the engine and onto the tarmac.

Unsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. A boost leak from the factory diverter valve will cause the ECU to drive the turbo harder to compensate for the loss, resulting in higher turbo RPM, more exhaust backpressure, and hotter compressor outlet temperatures. So even though your tune might still hit target boost, a diverter leak means the turbo is more stressed, and the engine makes less power.

The DV+ replaces the factory diverter’s loose-fitting plastic valve with precision CNC machined metal components and a durable elastomer piston seal. Because the DV+ design uses boost pressure to force the piston shut, it doesn’t matter how much boost you throw at it – a DV+ won’t fail, leak, or blow open.

Low sound. BIG PERFORMANCE. The DV+ is designed for performance, not noise. Recirculating the vented air back to the turbo intake keeps the sound to a minimum. If you have an aftermarket intake , you will hear the DV+ vent softly, but if you’re looking for performance AND maximum sound, check out the VTA or DVX range.

Durable. Dependable. Reliable. The combination of precision manufacturing, attention to detail, and robust materials mean the DV+ will last a lifetime. So does the warranty.

High flow, tune on! Whether your engine is stock or tuned to within an inch of its life, the DV+ has the flow capacity to support whatever boost your turbo can provide.

Bolt-On Performance. The DV+ is available in a huge range of direct bolt-on kits to suit cars with a factory-fitted electronic diverter valve. Same features, same benefits, just different fitment options. Use the vehicle search function at the top of the page to find a DV+ that fits your car

DV+ vs everything else

There are other aftermarket products that look similar to a DV+, which can lead to confusion about what the DV+ is and how it compares.

DV+ vs “BOV Spacers”. A blow off valve spacer is not actually a valve. It is a single-piece spacer fitted underneath the factory diverter valve that directs vented air to the atmosphere for a blow off sound. However, it does not address any of the performance or reliability shortcomings of the factory diverter valve.

The DV+ is the opposite of a blow off valve spacer – it offers performance and reliability improvements over the factory diverter valve, but it does not make a blow off sound. GFB’s VTA and DVX range however do offer a blow off sound AND the same performance improvements of the DV+.

DV+ vs cheap counterfeits – whilst our patents should be enough to keep other manufacturers honest, this isn’t always the case – the DV+ looks simple, making it a tempting target for counterfeiting.

The reality is that simply copying the DV+ isn’t adequate. There’s more to making a DV+ reliable enough to earn its lifetime warranty than making it look the same. Insist on genuine GFB products for the best performance and protection for your ride!

DV+ vs other aftermarket diverter valves – the DV+ remains the fastest actuating, highest flowing, and most cost-effective electronic diverter valve solution on the market.
