Good work with the JBD! You're going to love it; transforms the car under throttle.
Personally, I think you're better off with the stock filter. Why cake up your engine for a little bit of extra intake/turbo noise? Put the 50 bucks toward gas and lunch for when you take an accidental road trip while enjoying your JBD.
