I had completely forgot that I started this thread. Anyways, The Fram filters that I use to buy were junk, compared to a WIX or Purolator. These other 2 brands were substantially (sp) heavier. As I probably mentioned before, the Fram that I cut open had a piece of aluminum as a spring inside. Whereas the WIX had an actual coil spring and there were twice as many holes inside to let oil flow.
