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.
 
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” 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.
