Engine Bay as of when I bought it; Weapon-R intake. I'll have to replace it, probably with a stock air-box, once I move to SoCal, even though the loss of the awesome green paint on the tube will result in a serious power loss of at least 35 HP :( Actually, this piece of ricer crap is probably actually COSTING me HP right now, since it's not really designed for a rotary, so I will probably replace it sooner.
