When you look it at without brand hate glasses on, the filters made by Mann-Hummel (and the brands they acquired) seem to have more issues than Fram ever had. The two big things with Fram was the wire baked OG Ultra and Titanium going away, and of course the ruffled leaf spring. People lost their freaking minds over the OG Ultra changes, and of course the whole "wavy pleats" meltdown thing, lol. Seems lately that Ultra C&Ps don't seem to have much in the way of wavy pleat, so maybe Fram addressed that with a tweak in the media make-up.
Fram never had ruffled leaf springs until Champion Lab started making the Fram filters. Other Champ Lab brands like Amsoil, Royal Purple, ACDelco, etc have been shown to have the ruffled leaf springs also. Then of course there's the ill formed louvers thing, which seems to be a thing with about any brand that uses a louverd center tube. I'd rather use a Fram Endurance with a ruffled leaf spring than a M+H made filter that could tear the media or shed off junk potting material from the end caps. If Fram (and others) could get Champ Labs to stop stamping ruffled leaf springs that would be a good 1st step. So, Fram isn't the only filter brand that has gone downhill lately, and the main cause is due to what I already said about trying to cuts production cost to maintain profits and stay in business in today's ecomomic environment.
