Haven't driven it yet. Started it up and reved it, definately the most BOV sound I've had yet. (GTR BOV with 3" metal intake pipe,) and there'll be spoolings.
As far as Wasps go, I'm thinking it may suffer due to warm air (no shield) and K&N Panel filters in a stock box should be good for extra Wasps anyway (over stock filter) plus the whole cold air thing.
Should be fun for a while though.
