This blow off valve sounds better than any other I've ever owned. Gives off a loud chirp, some of my friends say that they hear the bov before they hear my exhaust when I pull up. Easy install, everything needed was included. Great purchase.

  • Q: hks bov  supraclipse86 14 days ago

    Answer

    can the hks bov be tuned properly with the cobb accessport?


    • A: You will need a protune to run this BOV. The ots maps will not work in unison with this.

    Hi I have a 4EAT Automatic WRX with a stage 1 OTS Cobb tune. Would this be compatible with my car? Would it do any good?

    Answer

    Was just wonder if this will fit my 2006 wrx & will I need to buy a gasket ?


    • A: This is confirmed to fit a 2006 WRX. It does not come with a gasket so you will need to buy a BOV flange gasket.

  • Q: Safe  DAM2014sti 3 months ago

    Answer

    My 2014sti is sitting stock. Are there any issues installing this on my STOCK sti?


    • A: You will want to have the vehicle professionally tuned if you install this BOV. Subarus tend to have AFR issues if you switch from a recirculating BPV to atmospheric BOV without tuning.
