GFB’s DV+ solution couldn’t be simpler - keep what works and replace what doesn’t.
Worldwide Patent and Design Patent Pending
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.
Many late-model European cars use ECU controlled solenoid-type diverter valves. This is a good concept because the valve can react very quickly and it only opens when it needs to.
However, there are some problems with these valves. There are typically two types of solenoid-actuated diverter valves found standard on VAG and European cars, both of which have their shortcomings.
Common OE Problem #1
The diaphragm types are commonly known to rupture, especially when boost and temperature are increased as a result of chip tuning.
Common OE Problem #2
The plastic piston-type leaks far more than most people realise (by design, not from wear), and doesn’t always close after a high-boost gear shift.
Additionally, in both cases, the solenoid on the OE diverter is directly connected to the valve mechanism, which is not ideal because neither it nor the return spring are strong enough to open and close the valve reliably at high boost.
With problems like this, you can see why other aftermarket manufacturers assume the best solution is to replace the factory diverter entirely. Unfortunately though, whilst their replacement kits might be stronger than the factory diverter, their slower response speed and lower flow do not justify the extra cost and complexity - more of a compromise than a solution.
GFB has taken a different approach to deliver a complete solution that solves existing problems and improves performance, without compromise or a hefty price tag.
The DV+ addresses the factory valve problems with a very simple and elegant solution. Keeping the factory solenoid retains all the benefits of the stock system, and replacing the valve parts with indestructable metal components ensures strength and reliability no matter how much boost you run.
That's not all. Rather than using the solenoid to directly actuate the valve, we’ve introduced a unique “pilot-actuation” system. This means the solenoid controls the air pressure that is used to open and close the piston, so it doesn't matter how much boost you push through it, the DV+ will open and close reliably without ever exceeding the solenoid’s capability.
This feature also improves on the factory system by opening the valve progressively in response to boost pressure, so it only opens as much as required to get the job done (the factory valve simply opens and shuts, it cannot partially open if boost pressure is low), resulting in better throttle response.

BMW B58 3.0L Charge Pipe - Wrinkle Black addresses common issues with the factory plastic charge pipe, which is prone to blow-outs and can lead to engine limp mode and performance loss. This high-performance upgrade by Active Autowerke features a robust all-aluminum construction that enhances durability and prevents structural failure. The CNC-machined connection ensures a precise fit and reliable seal at the throttle body. With wrinkle black powder coating for a sleek, OEM appearance, this charge pipe improves throttle response and performance, making it a superior choice for your BMW.
This kit from Active Autowerke replaces the weak plastic charge pipe with a new aluminum part, secured with a high-quality silicone couple. When you're building a high-powered turbocharged engine, or even just looking for peace of mind on a stock application, durability modifications are just as important - if not more important - than adding power. If your charge pipe fails, it results in a huge vacuum leak that sends your ECU into limp mode, diminishing performance significantly. Don't wait - upgrade your charge pipe today!
This product fits the following BMWs:
2016+ F87 M2
2014+ F22 M235i
2012+ F30 335i
2014+ F32 / F33 / F36 435i
GFB is proud to introduce an extended DV+ range, offering a direct-fit solution for the factory diverter valve used in a wide range of European vehicles. This innovative product is engineered to enhance both performance and reliability.
Specifically designed for the N14 MINI Cooper S/ JCW Engine, GFB's DV+ is the ideal solution to optimize your vehicle's diverter valve.
Turbo vehicles often suffer from heat soak - methanol injection systems help cool the intake charge, and increases your engine’s knock limit – giving you a failsafe against high boost detonation. Active Autowerke's methanol-water is precisely delivered and metered by its own electronic module, which measures boost pressure within the engine and controls the delivery flow to match both the engine load and demand as needed.
This methanol injection system fits the following BMWs:
1998-2006 E46 320i 323i 325i 325xi 330i 330xi 323ci 325ci 330ci M3
