Another US made TL14610 off my neighbor's 2004 Civic, now with ~85k miles on it. ~4500 mi interval. Out: Super Tech Full Synthetic HM 10k, 0w20. In SuperTech Full Synthetic 10,000 mile 0w20 and another TL 14610. Nitrile adbv still functioning, let sit in a funnel outlet down, next day opened couple inlets, lots of oil drained out. Louvers fine, with media removed get a more accurate view in my experience. For ~$2.40. worth that imo. As an aside, I see Amazon currently has the P1 PL14610 for $2.75, lowest I can recall. I'm getting a few.
