Here's two more to the list that are still wire backed Ultra's. My part number is not a small filter it's a regular/medium sized cartridge. I'm leaning more to the idea Fram has plenty of supplies of these filters or are low sellers so not worth the switch.I believe it has been posted here the XG16 and 8A remain wire backed, likely due to the depth of the pleats. I haven’t been able to confirm as Ultra boxes are sealed.
There may be other sizes that did not transition as well, an extremely small filter would seem a likely candidate.
At any rate, if true, First Brands has inadvertently verified the new Ultra is inferior to the original. Which is consistent with what has been seen in C&P here.
