Don, part of it is that K&N simply doesn't like selling to people, so i'm stuck with one of a couple sources to buy them from. i think autozone is incorrectly retailing at wholesale. i think i pay like $28 or $29 for them, given that i offer them at $41.
more about the K&N thing. i was working on this custom project and wanted samples of a couple different filters with a follow on order for 100 pieces to follow. they told me to buy them from a proper wholesaler. they didn't care that none of my vendors even bothered to carry the filters i was looking for (nor were they listed in said vendors catalogs, so they'd have to create a part number, blah blah). so for said project, i bought uni filters. :
