That minimopar link is as worthless as any of the other "oil filter comparison" websites out there. I've said it before, and I'll say it again: No testing equipment means no testing was done.
The author DOES mention SAE testing, but then *sort of* dismisses it. He mentions that the SAE tests are done to ensure the filters meet the criteria set forth by engine manufacturers, but then goes on to say that the testing done has "several shortcomings".
I would really like to hear what an engine manufacturer, (or SAE testing engineer for that matter), would have to say about the "cut-it-open-and-have-a-look-inside" methodology. I'm sure they'd toss their specifications and various testing apparatus' right out the window.
A couple of my favorite quotes by the author:
So...he cuts open a filter and spreads out the media to measure it
But....he also says this:
So....he's comparing media surface areas, while simultaneously acknowledging that different filter media performs differently, AND....adding that there's no way of "usefully identifying" different types of media by VISUAL INSPECTION.
I've seen the minimopar link, (and several other similar ones as well), posted on several forums over the years. I cannot understand the "legs" these sites have, and I often wonder if the people that keep linking to them, (with good intentions no doubt), have ever really sat down and thought about what these sites contain as far as useful information goes...

Probably the most important value here is the element surface area.

But....he also says this:
There is no way of usefully-identifying the media types by visual inspection.
