GFBs DVX takes the extremely popular DV+ Diverter Valveand adds dual venting outlets along with our patentedVenting Bias Adjustment System. So not only do you getIMPROVED BOOST HOLDING and THROTTLE RESPONSE, youhave total control over your BLOW-OFF SOUND VOLUME!

WHAT MAKES DVX DIFFERENT TO ANYOTHER VALVE THAT GOES WHOOSH?

• The DVX is not just a noise maker (like BOV spacers) – by modifyingthe valve operation method it offers the same PERFORMANCEBENEFITS that the DV+ does.
• It retains ECU CONTROL for the fastest possible operation.
• No other blow off valve has the advantage of GFBs Venting BiasAdjustment, allowing you to alter the blow off sound simply bymoving the adjustment lever.
• Built to last.

GFBs DV+ design solves the longevity and boost leaking issues that arecommon with factory diverter valves, and also changes the operationmethod to pilot actuation (read about this below) to ensure better
performance on stock or modified engines.

Furthermore, these benefits wont cost you the Earth! Rather than throwingthe entire factory diverter valve system in the trash (like other manufacturerssolutions), the DV+ keeps what works, and replaces what doesnt.

WHAT DOES IT FIT?

The T9659 is a duel venting direct factory replacement fortheVW 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 redirectingthe air to atmosphere. Therefore, the performance deficienciesof the factory diverter valve design remain, and furthermore, the flow
capacity of the factory diverter is significantly reduced because of thesmall venting holes used in these BOV spacers.

ECU VS VACUUM CONTROL

Other BOV kits eliminate the ECU control entirely, using pure manifoldvacuum control instead. Whilst theres nothing particularly wrongwith this (thats how the majority of BOVs work), the ECU controlis MUCH FASTER, able to detect and respond to much SMALLERTHROTTLE TRANSITIONS and, since its available, why wouldntyou use it?

WHATS SPECIAL ABOUT OURVENTING BIAS SYSTEM?

GFBs patented Venting Bias Adjustment System is the only one ofits kind in the world. By using an internal rotating sleeve, the openingof both the recirc port and the atmosphere port can be infinitelyadjusted. This means that youre not stuck with a fixed 50/50 or100% atmosphere venting ratio; you can change it to whatever youwant! As an additional benefit, because the atmosphere outlet isa single large port rather than a series of small holes, the ventingsound is much DEEPER AND LOUDER than it is with a BOV spacer.

THE BOTTOM LINE IS…

The DVX offers a TRUE PERFORMANCE improvement, INCREASEDBOOST-HOLDING ability, and a blow-off sound that is COMPLETELYADJUSTABLE from factory-silent to ear shattering!
