#311422 Personally, i have a stock D series, full exhaust, and for the intake, i got a full long ram air from ebay for 40$ (changed the filter though to a K&N) and it works beautifully and much more flow than the stock air box. It goes down into my right fender (passenger side) infront of the wheel where the old big clunky airbox was.
