    QUESTIONS & ANSWERS

    • Q: TIAL Q BOV   Bov4 months ago

      Does it fit on Audi s4 3.0 supercharged
      • 0 of 0 people found the following answer helpful

        A:  Unfortunately, with it being a universal part we would not be able to confirm fitment with your vehicle.

    • Q: Flange   JoeJoe4 months ago

      I would love to install this on my stock TMIC for my 2018 STI, I was trying to look for a flange, but I don’t seem to find it. Help please.
      • 0 of 0 people found the following answer helpful

        A:  There isn't a true bolt on flange available unfortunately. However, Tial does offer a V-band flange that could be welded to a plate that is machined for the flange, but it would require custom fabrication work.

    • Q: BOV  dc2h2b1 year ago

      I'm running a mishimoto fmic setup on my 06 Sti. I would like to purchase this bov. Which flange that you guys have will work on my setup? Please lmk thanks

        A:  You will need a new flange but it depends on what size you need. I would measure the flange right now and compare it to the ones we have: https://www.rallysportdirect.com/scp/engine/turbochargers-and-superchargers/blow-off-valve-flanges

    • Q: 04 WRX fitment and Surge/flutter noise  tavo73 years ago

      The reason I am interested in this BOV is because ive hear them on others cars and they make this amazing flutter/surging noise and thats what i want. Is this the right BOV for that? I am also running a TMIC
      • 0 of 0 people found the following answer helpful

        A:  This is a fully atmospheric valve and it will have a loud vent noise. This is a universal fitment so you will either have to weld a flange onto your intercooler or purchase an adapter.

    • Q: fitment  Subie053 years ago

      Do I need a flange to run this on a front mount?
      • 0 of 0 people found the following answer helpful

        A:  Most front mounts using a stock BOV flange will require a flange to be welded on for the Tial or an adapter.
