I confirmed this finding yesterday when looking at four Titanium 7317 yesterday in local AAP yesterday. Went because of 25% off online code. Anyway, the two newest date code, no wire backing. Two older, but made this year, OG Ultra wire backed. Glad I brought a good flashlight to see down center tube, otherwise wouldn't have been able to tell. As I currently have a large stash of oil filters, didn't bite on the two OG for ~$9.40. Good price for the OG Ultra media.
So, the changeover to current Ultra media is underway for the AAP Titanium.
OG media element lasted longer than I thought it would.
