I got my filters from AutoZone, 25.00 each part# RU-1750. They arrived in one day and look great, I'm re jetting this weekend. I just cut the airbox section off of the battery box and kept it. fit was great just had to secure the front of the battery box to the carbs. I've got some pics in the members bike section.
Same part number? It might fit a car somewhere. I was told a while back that a 700 Volvo heater fan ($80) was the same as Chevy Celebrity ($26). I had the parts store pull both numbers and compare. That chevy fan is still going 10+ years later.
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. :
I had a hard time tracking down anyone that would even consider a special order for these filters. Many retailers said that they only sell auto filters, and I would have to go to a moto shop. K&N was really nothing but trouble. I just got lucky with Autozone.
