I found this volant intake, but it says it has a box not just an open filter, but the part number is screwy. The part number is VOL-19630 on the Volant site they say it is for a 02' 4.0, but the last two numbers on all the other part numbers for every other intake seem to coralate to the litters in the engine, i.e. all 4.0L models have a part number of VOL-***40 all 5.4L have VOL-***54. I would rather have the box, but I am not sure if this is true or not.

Also on TPC.com they make it seem like it has a box, and only show it with a box, but don't list a part number. Guess if I bought it and it dosn't have a filer I could return it since it isnt as discribed.
