I'm really not sure why some OEMs and filter manufacturers are having issues with this. My god daughter's Benz has a cartridge filter, and I've never seen the slightest pleat wave. So many other ones we've seen here routinely look like someone sat on them. Either some OEMs should stick to ordinary spin ons or some filter manufacturers need to go back to the drawing board.
Perhaps each "sat on" filter needs to be mailed to the head of engineering of the OEM in question.
Garak, this seems to be a common theme for some cartridge filter applications.
To succeed, the OEM must communicate clear specifications to the filter manufacturer and the filter manufacturer must meet the specifications.
I like your plan to start with the head of engineering of the OEM in question.
