But the fact remains that the way the pleats are held together are completely different and the absence of the string (which is a Purolator giveaway, the Mopar I cut apart had the string and looked very similar to the Purolator).
To me this says 2 different lines that the media is done on.
I have not counted any other AA or PP filters pleat count, but on my Hyundai filters, they are always the same. I currently have a Pure one on my van now, and another going on next change, bought at different times at different stores, so I will see how their pleat count compares. I would think as far as a QA thing, the pleats would have to be identical or no more than 1 different from one batch to another. Automated machines make it only 1 way, time after time.
I also just went and looked, they have different center tubes. One has smaller, but more, holes and the ADBV has different numbers on it, even though they appear and feel the same.
BTW, I really do like the grippy stuff on the can, they all need this on them.
Also, I wounder why AA does not offer a Pure 1 equivalent (kinda like NAPA and CarQuest do with the Wix filters)? A Pure 1 quality filter for less than the Pure 1 would be nice.
