I just cut open an (newer) XG7317 I pulled off my son's Mazda that had been on for 10,000 miles and I can say after using the Ultras for as long as I can remember, I doubt I'll be using them ever again. I wish I had taken pictures and posted them here. No tears, but plenty of waves in the pleats and I was able to make a tears with a shocking lack of effort. I'm talking just very mild pressure with a finger and I was able to tear the media right off the endcaps. I miss the wire backing. I defended them when they changed but after seeing one after using it, I'm out. This is not a premium filter anymore.
