Based on this thread, First Brands now seems to be seriously mixing and matching Fram/Champ Labs construction and calling it Fram at their whim. After seeing orange can ecores, I suppose seeing an Ultra the same way shouldn't be that surprising. I would like to see the internals of the Ultra ecore, media and end caps to see what they look like. The materials used for both.
As for Frams now with louvers on metal cores, get used it. FB been moving in that direction, one that Champ Labs with metal cores have been using for a long time.
