need open intake

I have an 88' 4.0. I need an open air intake. I have had Rusty's in the past, before my snorkle. I also had the Hesco from thinkjeep.com. Anyone know where I can get one? Or what I need to make one? Thanks Juice

www.turbocity.com sells a air tube setup for the 87-90 models if that is what you are looking for.

I cut the rubber piece off behind the ribbed part, and clamped in some 3" pvc. I needed to use a smaller diameter pipe inside the big one at the filter end because the filter is 3"OD. it's a rice-burner filter from autozone. A HELP PCV elbow was used for the CCV. the heat/mud shield is a piece of unrolled stovepipe. I got everything for ~30 bucks, filter, pipe, elbow, hoseclamps, stovepipe, rivits, and paint.
