Are there any differences between the Fram, Motorcraft, Purolator brands?
there is a difference, usally it’s in the orfice size of the valve and using a “cheap” one like the fram can and will pull to much vapor thru the system and clogg-up intakes and plenums…stay wth the oem Ford/Motorcraft D9ZZ-6A666-A and DONT forget to change the PCV trap(metal screen) E6ZZ-6A631-B located under the PCV valve, most people dont even know it’s there…..
