    Great Kit 2 months ago

    Really great kit. Awesome quality, easy install as long as you left the recirculating line in (unlike the previous owner of my Bugeye) but still an amazing piece.

    Worked out Great! 4 months ago
    NathanK
    It was fairly easy to install, sounds great and has some awesome pops when you open it all the way up and have the spring a bit loose. I would recommend having 2 or 3 people for the install as you will most likely need help holding the tubes and intercooler pieces up.

    Sounds awesome! 7 months ago
    Bald Eagle
    I really loved the idea of being able to adjust how much I could vent or recirculate and change how loud the blowoff would be. It was very easy to do and drastically changed the noise level as well. Cranked all the way open it was very loud and would get some crazy backfire going. I usually only had it about 30% open which was perfect. Everything was great with it until I took my car to get tuned at simple performance in Salt Lake and they smoke tested my car for boost/air leaks and the valve wasn’t sealed up completely. Apparently it’s a common issue they see on the GFB valves. You can risk it and might get a good one but I’d just go for something else. I currently have the turbosmart 50/50 valve and it works perfectly, it’s not as loud but is better built.

    Good oem replacement 1 year ago
    BooSTI
    Been running this for about 3 months now and so far it's definitely perfect for a subaru replacement. Anything over halfway open venting to atmo starts making the car back fire on deceleraton since the maf is setup for recirc but the option to vent 0% to all the way open is very nice. No problems leaking with the provided gasket. Would recommend to anyone replacement an oem recirc valve. The sound isn't bad but it's not anything out of the ordinary so if you want that whistle your only going to get the air shooting sound out of this.

    Will this fit a 2013 STI Hatch? I know it's not a direct fit but can you buy an adapter?

        A:  You should not need a tune to install a blow off valve but you should always consult with your current tuner.

    • Q: Direct Fit?  chrishardyamg8 months ago

      Will this fit a 2011 STi Sedan, i know it says 2004+ but just want to confirm before ordering
    • Q: Gasket  Chief10 months ago

      So I don’t think mine came with a gasket? Where is it located in the packaging? All it has is a small Oring where the valve connects to the intercooler.
