I'm making my own. I bought a cheapy "performance" intake kit for Chevy TBI's (that part doesn't apply to you) off ebay for the peice that bolts in place of the air cleaner, then the reast is 3" ABS pipe and elbows. The filter box is a scrap peice of 6" well casing from a local well driller. I'm still working on it. Hopefully I'll have it done in a couple weeks.
