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”?

  • The DVX is not just a noise maker (like BOV spacers) – by modifying the valve operation method it offers the same PERFORMANCE BENEFITS that the DV+ does.
  • It retains ECU CONTROL for the fastest possible operation.
  • No other blow off valve has the advantage of GFB’s Venting Bias Adjustment, allowing you to alter the blow off sound simply by moving the adjustment lever.
  • Built to last.
T9661 DVX DIVERTER VALVE

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 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 trash (like other manufacturer’s “solutions”), the DV+ keeps what works, and replaces what doesn’t.

WHAT DOES IT FIT?

The T9661 is a dual venting direct factory replacement for the valve used on Hyundai, Veloster and Kia

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 flow
capacity 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!

      I gotta say guys, all of you did a great job making this product available and guaranteed fitment for the 2015 Sonata 2.0T . I am extremely happy not only how my BOV sounds when letting off the gas, but also how the turbocharger sounds when hard driving it. I really appreciate the hard work, dedication, reliability and fast shipping! I look forward to keep doing business with you in the near future.

      I have had this DVX fitted to my vehicle for just over a year now and its still going strong. Must admit the DVX is fitted to a vehicle that it was not intended for but looking at stock valve being identical, and after speaking before hand with GFB about dimensions, design etc i confirmed it also will fit and work on my Vehicle which is a 1999 Volvo S40 T4 there customer support is the best i have dealt with including after as they followed up with how its going. After installing i maintain a solid 18-19 psi boost to the red line, I can also maintain boost better at gear changes. Being a twinscroll there was already little lag but now there is next to none. During normal driving since the Volvo is very sensitive to any changes and has a MAF i have to have the vent closed otherwise engine becomes close to stalling at slow start stop traffic, this is with the pretension screw all the way in (the vacuum is 20-30in-hg so valve sometimes doesnt fully close). But when driving hard i can have the vent all the way open which is kind of needed, and i still get great response, i get very sharp vents, no turbo chatter and only drop to 15psi during gear changes which makes for much faster acceleration. So happy to say the DVX valve is a great design and can handle quite high boost and maintain solid reliability. It truly has made the old Volvo a entirely different beast.
