Some of the Fram cartridges have a plastic mesh backing. I've never cut mine, but others here say that plastic mesh is a bugger to cut open. I haven't compared the length of the Fram to the Wix or Mopar, but I think the Fram might be a little longer. The Ultra I used on the Caravan was a bit more wavy than the other filters.
