More stuff online I've run across over the years. You guys will form your own opinions. What this does not show, which you can find online videos of, is how some filters have very poor quality media, parts are glued together, gaskets that get stuck to the oil filter mount which you have to scrape off, and gaskets that fall off. Not all tension springs and clips are equal. The best videos also show what those filters look like when cut open after XXXX thousand miles. Even the canisters aren't equal. I recall some canisters being so flimsy that when I tried to remove it with a filter wrench, the canister crushed like a beer can.
