If you can get a WIx/Affinia or Fram one, they're not bad-but the Purolator ones are like everything else they build, not worth it. For example, for the GMC 6.2 in my sig (or most other older small block Chevy engines) AAP lists both the 85060 Purolator CQ Blue, and the superior Fram/Champ 85061 CQ Blue (which has the same media as a Mobil 1 filter).
