I use K&N oil and air filters on all of my cars. I sometimes cruise eBay for my particular part numbers, and sometimes get lucky and score a K&N HP series filter that fits my junk for under $10 shipped. This time I found an HP-1004, that fits my Optima and would also work on the wifeís Capri convertible, and if Iím feeling extra hotrod-like, also fits the zero turn mower. I won it for $1 plus $5 shipping, no big deal, and it arrived today in a non padded envelope. The box was torn up pretty good, but hey... itís a K&N. Itís thick and strong and can get tossed around a bit and be ok. I open the box up and find a dented up Fram PH3593A. Well nuts. If it wasnít all dented up I would have just chalked it up to experience and used it on the zero turn. But I donít use dented filters. Oh well. Live, learn, and experience stuff. That is all. Feel better now that Iíve shared my $6 lesson. Good day folks.
