I'm down to my last couple of PF24s from when I bought out all Rock Auto had which was probably like 10-12 years ago. But, I do know at one point they did have some that were made in mexico, and as I recall, they are stamped 'made in mexico'. I heard they were substandard, but I have yet to see one cut open. I also understand that they don't source them from that manufacturer anymore, due to whatever reason.

I cut open all my filters, and have never seen a collapse in any that I have used from my batch. I will be buying some here soon, and before I install one, I will cut it open and see if they're the original design.

If you're concerned about the AC Delcos, the next choice is easy, NAPA Gold.
