Not a good filter at all.  Recently took apart 5 different makes of oil filters, all similar to this.  After examining them it is apparent that Fram is not what you would think they were.  fram filters have 1/2" spaces in between the filter bends.  all the rest were nice and tight 18" or less.  also the over flow valve on the fram is poorly constructed.  most were built in to the filter but frams just sat in there along with the sealing o-ring. still doing the job but not as effectively.  An instructor told me that they put the black grippy stuff on there because it is junk metal and if you try to use a filter wrench it will rip the metal.  I can't confirm that seeing as I used fram filters for a little bit and never used a wrench to remove.  thanks to the black stuff.
