GFB’s DVX takes the extremely popular DV+ Diverter Valve and adds dual venting outlets along with our patented Venting Bias Adjustment System. So not only do you get IMPROVED BOOST HOLDING and THROTTLE RESPONSE, you have total control over your BLOW-OFF SOUND VOLUME!

WHAT MAKES DVX DIFFERENT TO ANY OTHER VALVE THAT GOES “WHOOSH”?

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” (read about this below) to ensure betterperformance 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 trash (like other manufacturer’s “solutions”), the DV+ keeps what works, and replaces what doesn’t.

WHAT DOES IT FIT?
The T9659 is a duel venting direct factory replacement for the VW MK7 Golf R and Audi 8V S3
WHY NOT JUST USE A SPACER?
There are many “BOV spacers” on the market that make noise. However, they do this simply by using the factory diverter valve and redirecting the air to atmosphere. Therefore, the performance deficiencies of the factory diverter valve design remain, and furthermore, the flowcapacity of the factory diverter is significantly reduced because of the small venting holes used in these BOV spacers.

ECU VS VACUUM CONTROL
Other BOV kits eliminate the ECU control entirely, using pure manifold vacuum control instead. Whilst there’s nothing particularly wrong with this (that’s how the majority of BOVs work), the ECU control is MUCH FASTER, able to detect and respond to much SMALLER THROTTLE TRANSITIONS and, since it’s available, why wouldn’t you use it?
WHAT’S SPECIAL ABOUT OUR VENTING BIAS SYSTEM?
GFB’s patented Venting Bias Adjustment System is the only one of its kind in the world. By using an internal rotating sleeve, the opening of both the recirc port and the atmosphere port can be infinitely adjusted. This means that you’re not stuck with a fixed 50/50 or 100% atmosphere venting ratio; you can change it to whatever you want! As an additional benefit, because the atmosphere outlet is a single large port rather than a series of small holes, the venting sound is much DEEPER AND LOUDER than it is with a BOV spacer.

THE BOTTOM LINE IS…
The DVX offers a TRUE PERFORMANCE improvement, INCREASED BOOST-HOLDING ability, and a blow-off sound that is COMPLETELY ADJUSTABLE from factory-silent to ear shattering!

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:
 

If you’re looking for the performance benefits and fit of a DV+, but also want an adjustable blow-off sound like the Respons, the DVX is the only choice.
The DVX range covers vehicles that can’t fit or use valves like the Respons or Deceptor Pro II, and each version in the range is designed specifically for its application, ensuring the best fit and performance.

Increased boost holding and throttle response with total volume control!
GFB’s DVX range takes the extremely popular DV+ Diverter Valve performance and fit, then adds our patented Venting Bias Adjustment Systems from the Respons range of valves. This feature allows you to infinitely vary how much air is recirculated, and how much is vented to atmosphere, giving you total control over your blow-off sound – completely adjustable from silent to ear shattering!
The DVX is not just a showy noise maker either. Using GFB’s proven TMS Technology, whilst retaining ECU control, the DVX solves all the performance and reliability issues that are common with factory diverters AND gives you a blow-off sound that’s completely adjustable!
