Honda Civic Gen 10 1.5T GFB DVX Diverter Valve
Go Fast Bits' DVX is the last diverter valve you'll ever need for your 1.5T Civic! The factory diverter, or bypass valve, is a cheaply made diverter valve made from stamped steel and use a softer rubber diaphragm to seal boost. GFB's DVX is machined from billet aluminum and uses a metal piston to seal boost. This piston is faster reacting and less leak prone than the factory diverter valve.
The biggest feature of the DVX is the adjustability it offers with a simple flip of a switch! By moving a small lever on the top of the valve it can be changed from 100% full recirculation like the factory valve to a 50% recirculation and 50% vent to atmosphere valve, or anywhere in between. The 1.5T in the Civic uses a MAF sensor so we only recommend running the DVX no more than halfway open to keep fuel trims in check and avoid throwing any check engine lights. Even with the valve just a quarter of the way open there is a significant difference in sound so there is plenty of room to tailor the valve for your desired sound level!
