I've looked at a 95,96,97, and 99, trying to figure out the point of that small opening in the airbox, as it certainly looks like some ductwork should attach there. On the 95 and 96, there's a cutout in the metal bulkhead, just aft and to the right of the headlight, but a plastic cover is affixed to the sheetmetal, blocking the opening. On the 97 and 99, the airbox still has the opening, but the sheetmetal has none. None of the 4 had any ductwork connected to the airbox, even though it looks as though a couple of screws and a short piece of duct would get a lot more cold air than they could otherwise get with the airbox situated as it is. Is this something only CA jeeps would have been equipped with? I had thought cold air duct, but perhaps this warm up assist connected there instead? I've wondered about that odd layout since I bought it.
