[MODERATOR NOTE: I'll continue to allow editorials on this subject, with the reminder that they are editorials. - Mike Substelny] There ARE quality aftermarket oil filters out there. But, NEVER use a Fram filter. Years ago they were a quality filter, but they were bought out and the quality dropped. They're now riding on that earlier reputation and lots of advertising. They use cardboard for the end caps of the filter element instead of stamped steel like most manufacturers. Here is a pretty good comparison of a variety of filters: http://www.dorianyeager.com/oilfilterstudy1.html It was originally written by a Mopar enthusiast, but has been copied to this location. It does a comparison of construction quality, and the filtration material used. It's not a perfect study, but it does allow you to draw some conclusions about the various brands of filters based off of their construction quality. That said, you can't go wrong with a filter from the DeLorean parts vendors. But, you can also find quality aftermarket filters if you go looking for them.
