GFB DVX Performance Diverter valve with volume control for Hyundai and Kia

Key Features:

• 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.

WHAT DOES IT FIT?

The T9661 is a dual venting direct factory replacement for the valve used on Hyundai 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 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!
