When I get home I will take a pic of the 2 filters with the part numbers one will be on the new style FRAM filter that I speak of that I use on my civic and the other will be of the S2K filter that I use on my Hybrid Accord. I have read that some dealerships carry this honeywell made filter that you speak of but here in California we have 2 types of filters FRAM and S2K (made by toyo roki). I may not work at honda or have access to honda's database of part numbers but I have been to may different dealerships and they all have the new style FRAM filters and the S2K filters only. I have run into 1 Honda dealership in San Francisco that still had the older style filters.
So in your honda database please enter part number 15400-PLM-A02 that is the new style honda filter made because of the K series engine that is made by fram.
Old OEM universal filter = 15400-POH-305
Made by Filtech (For all Hondas)
New OEM universal filter = 15400-PLM-A01
Made by Fram (Replaces 15400-POH-305. Except not for use on the S2000)
New OEM "S2000 only" filter = 15400-PCX-004
Made by Toyo Roki (Same size as old)

I think I see what the problem may be is that you guys are getting part number 15400-PLM-A01 and in California we are getting 15400-PLM-A02
