    What blow off valve for 2007 sti

    Ive just bought a 2007 sti and want to know what blow off valve I should buy. It is not modified just standard. I like the noise and am hoping this part is good for the turbo. Please give me information to help

    whatever you do, don't get one that vents to atmosphere, because your car will run rich between shifts causing it to bog down. no fun.

    The HKS SSQV is one of the worst valves on the market in terms of leaking.

    TGV deletes is not a very good modification on a stock car. First, it's a long install, and with a car still having the two OEM catalytic converters, you're not going to gain nearly anything. Also, this modification requires a tune, as it will put you in limp mode without it. You can easily turn off the CELs related to the removal of the TGVs, but you'd need to be comfortable editing a ROM and reflashing your ECU.

    On the 03-07 models you can also do an intake silnecer delete. It's completely free and amplifies the stock bpv sound

    the intake silencer delete gave me the sound i was looking for, and it's not too annoying for other drivers

    just run 3inch turbo back, youll hear the turbo spool and all. and between shifts it kinda almost sounds like an aftermarket blow off valve. ive had people ask me what b.o.v im running on my 02 wrx, so you should definately be able to hear it spool in an 05 sti.

    p.s why does everyone say to get a cai to hear it? i still am running stock intake and you can hear my turbo spool with ease

    A CAI will force you to remove the silencer in the fenderwell. The intake will create a "whooshing" sound different from that of the turbo.

    I loved the difference in sound I got when I installed my APS 65mm CAI - unfortunately, it was only on the vehicle for a few days before the EWG got installed, and now I hardly ever hear the intake.

    Moved to engine mods - just a heads up this will probably get merged in the huge BOV thread.
