  • Allows you to control the amount of air that is vented to the atmosphere, or recirculated back into the intake to control the venting sound based on driver preference
  • You can achieve a vented blow-off valve sound without triggering a check engine light or other problems such as running rich or stalling
  • New hardware and tool will be provided to make this blow-off valve ready for the installation

    Great Product! 1 year ago

    Very happy with the quality of the GFB. Fitment was great. I highly recommend the product! Only thing I will warn about is that you will more than likely have to have a cobb programmer or some other way to tune the vehicle after install. Even though in the GFB instructions it tells you can adjust it until it no longer backfires when you shift, but the only way my car didn't backfire is if the GFB was turned completely to recirculate. Which was fine for me because I was getting the car pro tuned on a Cobb accesport anyway. But Just wanted to let people know that.

    Install and “tune” took less than 30 mins. Great piece from out of the box. Good solid piece. Piston seems to be very durable. Set at between the softest and the hardest setting. Stock 09 wrx with catback and gave that WOOSH sound that I always wish I had in my hondas. Does anyone know if it has any alignment/clearance issues with the process West verticooler.

    So it appears to be a well constructed product but this did not work for me as the stock spring is to stiff for my setup. I am running a 2008 WRX with a process west intercooler and a Cobb tune and at the softest spring setting I was getting turbo surge. When physicaly pushing in the piston with my finger it feels pretty stiff. At 50/50 it has a good blow off sound, but not much louder than the blow off sound I get from my cob intake. I just ordered the soft spring and will try that out and see if she works better. Will update review!

    GFB TMS Respons Hybrid BOV 2 years ago

    Great product. Mine had a slight scratch on the bottom flange from MFG but didn't seem to affect performance of the BOV. Adjustments can be made very fast and makes it very convenient. Highly recommend.

    BOVs are the easiest thing to install. It's difficult to see where the adjustment valve is when it's mounted due to the trumpet position but it's doable. The sound is nice. Not my favourite but I do like it still. I'm set to 50/50ish and get occasional backfires but it's not super choppy between shifts like a full VTA BOV is. Overall I'm pleased.

    QUESTIONS & ANSWERS

    • Q: Exhaust popping   Codes15 days ago

      I put this on my 2013 WRX and have it set to what looked like half circulating and half venting, and sometimes when i rev to around 35k i'll get a pop from the exhaust. I've been told its fine but just wanted to see your opinion. I have an Invidia N1 cat back and Invidia uppipe installed, along with a cold air intake and an accessport tuned to stage 1.
    • Q: 2011 WRX fitment  slowrx9203 months ago

      I have a 2011 WRX with various mods including a Process West verticooler, will this fit with my verticooler?
    • Q: Tune ?  Live free or die subie10 months ago

      I have a 2013 wrx turbo back 3" with cobb short ram and a stage 2 on the access port will I have to go get a pro Tune?
    • Q: My car is stock  totalynotchris10 months ago

      This might be a stupid question, but here it goes. I've owned the same 2009 WRX for two years. Apart from an exhaust that the previous owner had, the car is bone stock. I've been wanting to put on this specific bov on for a while, now. With it being stock, will there be any problems if I install this part without having anything else on?

        A:  No stupid questions here! You can bolt this right on and you will not have any problems at all. Give us a shout if you have any more questions.
