Like ever. My Sedona uses a large cartridge filter. A good quality filter like Napa Gold, Fram ToughGard, or Mobil 1 run at $10 or $11, if not more. The exception being WalMart who carries the Fram TG for $8 or $9. I've used Rockauto many times in the past, but never for oil filters. I just picked up 4 K&N oil filters for $4.04 each, PLUS a 5% off code, and saved a couple bucks shipping because I'm sending it to my place of employment. So ~$22 OTD for 4 high quality filters, including o-rings and the lot. Not bad. They had several other high quality brands too for cheap (Mann, Purolator, Beck/Arnley).
