Very easy to install! Added 4 washers to preload the spring before install. Bolted it on and adjusted the length of the vacuum hose, and that was that. It sounds great!! I've had it for a month or so, and never had a check engine light. Quiet when you need it to be, and hits that trademark blow off sound when you push it hard!!!

I installed the Turbo XS BOV a couple of days ago... I have to say this is awesome!! The whoops sound is really nice! I was having some after fire between 1st and 2nd gear ( have a turbo back exhaust) and after I installed 4 washers everything is much better now... Just ordered the short shifter pack! Can't wait for them... RSD staff is great, they answer all my questions and my product arrived on schedule! Thanks!

Super easy install with no problems. All my sensors are fine with BOV vs. a non hybrid. I also have done some other mods including the Cobb AccessPort. May need to add a washer or two now, but that's because I upped my target boost.

Great product! You really pay for what you get with this item. Now I know bov's aren't suppose to in crease boost but now I consistently gel 16 lbs of boost without any loss. Luvs it!!!


  • AnswerQ: noise  sniperchild00763623 2 years ago

    Dose this product actually enhance the noise that a blow off is supposed to do or is this just a replacement that looks fancy

    • A: This BOV is louder than stock and will have a sharper sound.

    • A: While not as loud as our full vent-to-atmosphere blow off valve WRX08-RFL, this valve is significantly louder than the stock bypass valve.

  • AnswerQ: Backfiring  semperfidevil41154 3 years ago

    I just installed my bov and its backfiring, what can i do to fix that???? Thanks.

    • A: There is no fix, that is a result to having a valve that releases air to the atmosphere or even partial air to atmosphere.

    How can i tell if the valve is closed at idle?

    • A: You can look at the piston movement through the side port to see if its opening or not from when the car is off to running.
