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!
Customer Reviews
Picked up a DVX to pair with my PRL inlet pipe, and I'm so glad I did. Fitment is a bit tight with one of the surrounding hard lines since the PRL inlet pipe is much larger than OEM, but otherwise it is perfect. Adjustable sound/blowoff is awesome. Even at full recirc it sounds much better/louder than the OEM BPV. I did not adjust the spring pretension at all and it has been doing fine. I've been running the adjustable venting at about 1/4 open and have not had any issues so far.
You can see the slight wear from the initial contact of the hard line. I have remedied it by applying some Tesa tape and prying the hard line out of the way slightly. Also, I did not realize the DVX came with socket head cap screws until after the install, so I just reused the OEM screws. I believe the included hardware will fit even though this product is not intended for the 1.5T.
