    I have been able to fix the issue that I was having with my 2013 wrx hatch, the bov was fine and works as it should! its a solid piece however the bottom plate still had its issue where it was not even all the way across and it had issues fitting in attachments made for it.

    Its alright, while it lasted 2 years ago
    2out of 5stars

    Alright, so I bought the BOV and flange from a highly reputable perfomance shop about 2 or 3 months ago. It was a pain to put on the adapter because the bottom plate of the BOV was too big and not consistent on how thick the metal is. I had to shave it down a bunch on one side of the BOV and a little on another to get it to fit. Let me tell you that thing really fits in there. Now after 2 months of driving around with it, im assuming the seal in the BOV went bad, when I get into boost, I can hear a larg ammount of air coming out of the BOV. Im going to see if I can fix it or just replace it with a different one.

    Overall the product is well made and the sound it makes is intoxicating. I have 2 friends that have this on their cars and it sounds ridiculously good. You'll be popping on and off the throttle continuously. The only issue I had was that I could not get it to fit with my PW Verticooler there just wasn't enough clearance. I'm sure there is a way to get it to fit somehow but not that I could see. Yes you have to buy the separate flange but that's why it's a universal part not a vehicle specific.

    I own a 2011 WRX, so if you have the same car or an 08+ read this before you decide on purchasing the part. This is not a bad review, but a heads-up that you will have to buy a few accessories. A flange, which has a part number mentioned in the review. And, a plug for the recirculating hose. It does have to be welded because our type of car. But, once I get this baby inside I will let y'all know my satisfactory with the item.

        A:  This does not have the correct style flange for your 2013 WRX. So, you would need to order ATP flange adapter (Part # ATP-FLS-176) to properly install this BOV.

    • Q: CVT WRX  IV5 months ago

      Will this run good with the WRX CVT because I’ve heard that it doesn’t and I wanna be sure before I buy.
      • 0 of 0 people found the following answer helpful

        A:  This should be fine on the vehicle as it is engine related and not transmission related, however you will need a custom flange for this unit as it does not have a flange attached for the WRX.

      Will this valve fit my 2016 focus st
    • Q: flange  Colbie10 months ago

      does it come with a flange, because the reviews keep saying it doesn't. If it doesn't come with on and is suppose to have a flange, will you send me a flange for the missing piece?
      • 1 of 1 people found the following answer helpful

        A:  This valve does not include a flange, and would require an adapter to fit most vehicles. We do carry flanges for various universal valves to fit certain vehicles: https://www.rallysportdirect.com/scp/engine/turbochargers-and-superchargers/blow-off-valve-flanges
