Not to be a dick, but BOV is worthless, until you get up there in highend mods. Unless of course you are trying to impress the guys at the local High School. Way to aim high. Besides, with the CAI you are going to hear the turbo spool up better, and the BOV as well. No need to waste money, not to mention the problems that may come with running even richer than we already do by venting. Now when the bigger turbo, pnp, fmic, etc... thats when you get it.
