  • New hardware and tool will be provided to make this blow-off valve ready for the installation

    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! 1 year ago
    5out of 5stars

    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! 2 years ago
    3out of 5stars

    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.
