Not sure if this makes any difference, and I am not familiar with the filtering efficiency or specifications of the filters. My observation was based on the physical appearance of the filter paper quality and pleating, which is not a scientific measurement at all. I just shopped this photo from my recent
clear oil filter video which shows the filter elements from the Purolators that I used for my 05 Scion TC. For the record the only difference between the Purolator line was just the filter media, the internals were exactly the same between all of them.
