I was checking out filters and I opened an ACDELCO Duraguard and immediately recognized it as WIX made, complete with silicon ADBV. I‘ve posted pictures of it compared to NAPA NASCAR Select which is WIX made also. The PF52 was the only one which looked like a WIX; the others looked to be of poor quality with noticeable amounts of excess glue spread everywhere around the joints (w/ nitrile ADBV). Cost: $3.28 for the ACDELCO @ Wal-Mart for what looks to be the same as WIX/NAPA GOLD.
