I cut open the used Honda Filtech that I took off my car today. I was just curious what was on the inside. I liked what I saw, and will probably continue to use them since they aren't anymore than a Wix at the auto parts store. The end caps are very similar, and somewhat thicker, than the e-core endcaps. The center tube would easily slide out, but fit snuggly into the base and the bypass on the end. It seemed to be a fairly solid built filter. I'm going to try and get a OEM Honda Fram next time. I don't know if I want to run it or just cut it open though?
Here's some pics, enjoy:
