This is a PO-9A, 3387A equivalent filter run on an 09 Equinox, about 5 months. No tears, tight uniform pleating. And while I've seen wider louver openings there are plenty of them and they open in two directions. Confident plenty of flow, no restriction. So the element itself quite good.
The one negative as you'll see is cuts in the adbv, which was still relatively flexible. The fix for this would be so easy. Just narrow the center tube outlet hole end slightly and decrease/eliminate the taper/bevel on it and the adbv won't touch the inner edge of the inlet holes. The inlet holes are not that sharp, wouldn't cut the 5 mil gloves I had on. It's just the direct pressure on them with the adbv from leaf spring. Even with that, no start up rattle in this GM thread end up application.
Replaced with some Havoline ProDS 5w30 I got for ~$8 jug on O'R closeout and a Napa Gold 1040 I got recently for $3.60 at local Napa 40% off sale. As far as oil and filter combination, likely the best OC the vehicle has seen in it's life.
