I usually buy OEM in a case off Amazon or Ebay for $40 for 10, and reorder when I get low. But one time I was between cases or something, and used a Supertech on our '11 Camry, which is a cartridge. Filter looked fine when I took it out after 10k BUT the o-ring on the cannister was shot after only 10k. It had gone square and there was no drag on the cannister as it came out. As a result I'm leery of using them again, certainly not without going 5k first and seeing if the o-ring has improved. I'm not sure if it's heat cycles or what, we usually rack up the miles in short order, so it's not like it was a 5 year old o-ring.
