    That is not an easily answered question. I would suggest you go to the HKS and/or Greddy websites to seek the answer.

    Also you should CLICK HERE and read.

    welcome.

    why didn't "your friend" create an account?

    BOV on a stock Subaru WRX or STI is peeing in the wind. In other words, it's dumb. Subarus don't like them, and tend to cause more problems, when used. Read the BOV thread: http://www.clubwrx.net/forums/engine...ght=BOV+THREAD
    located at the top of this forum....

    Merging..

    Anything Better than stock BPV?

    So I took everyones advice and I'm selling my HKS Blow off valve in 3 days. Therefore I either have to buy a oem bpv or something else to take its place. Since i have to spend some money anyway to buy the stock one, I was wondering is there anything better out there (Not a traditional bov, because I know you don't recomend them)?

    I'm running a catback exhaust, STI Top Mount and a Intake, if that matters.

    Thanks ahead of time for any advice.

    For stock or nearly stock turbo the stock BPV IMHO, is best.

    The only times that its not the best it at boost pressures of 20psi & above.

    Stock BPV is working well for me. 20psi and holding.

    why don't you just buy a recirculation fitting for the HKS and hook it up?

    Flutter with BOV and silencer delete

    when i'm in low boost, and i let off the gas, there is a fluttering noise coming from the passenger side of my car.
    i have a GFB BOV, that is fully adjustable, and i took the intake silencer, and i'm trying to figure out what is wrong.

    that's my car. you can hear the flutter really good at the last shift.

    That noise is normal with an aftermarket BOV. It could also be compressor surge. If you don't like it, put the stock BPV back on.

    That's your car telling you to take off the BOV valve because you're hurting it.

    but it only happens in super low boost, and when i'm boosting really hard it blows off like normal, instead of making that weird noise, and sometimes it will blow off and then make the flutter.
