20 years ago if i saw plastic inside an oil filter i would have thought it was junk today most engines have plastic in them and there are little to no issues..Those pictures you posted look like the boss could be a well made filter. I looked at a couple of the new Purolater filters and did not really like the tiny oil holes in the center tube. I will be cutting open the first one i get my hands on and report back. I am still not so happy with Purolater but if their filters prove to be good again i may give them another chance.
