My brother had some motor work done a year and a half ago and they guy at the machine shop had very strong feeling about not using Fram filters. Just figured it was someone who hated Fram. I then read this post here...http://www.forabodiesonly.com/mopar/showthread.php?t=28092&highlight=oil+filter
So when I picked up my motor from Hensley i asked what filter should I use they said they use Baldwin, but Wix is a close runner up. He said if you are in an absolute emergency situation dont use a Fram. I asked why and he said someone there use to be a rep from one of the filter companies and has cut open tons of filters and by far Fram is the cheapest. So, when I got home I did a little more research and found these links http://minimopar.knizefamily.net/oilfilter-fram1.txt http://minimopar.knizefamily.net/oilfilters.html
