Interesting Filter Discovery

[lubeowner]

Today I got in a Mighty M81 filter on a 1998 Durango. This filter was the Crysler filter in the Mighty line years ago and was superseded by the M4670 which most of you are familiar with. I know for a fact the M81 was discontinued over 6 years ago. I cut it open and am not sure what it is. It is like a Purolator/Fram hybrid. It had a threaded end bypass that was pretty marginal looking, cardboard endcaps, and a center tube that looked exactly like a Fram. It also had a string tied around the media like Purolator. The media was sealed together with a metal crimp. This might be the mystery filter line that Purolator used to produce in a now defunct plant that I have heard a few people here talk about.

Anyone here have any guesses on what this thing is, not a big deal but got my curiosity up.

I'm under the impression Champion also makes Mighty filters/.

They do now, but this one was definitely not a Champion. It was the older White can with red and gray striping. I dont think Mighty switched to Champ until 1999 or so.

question : is a 6 year old filter being abused, and had it suffered media failure ?

The owner coulda bought 50 of em when they went on half price and just now got around to using it..?
But if it WAS installed 6 years ago, now that would be interesting!
I've got SEVERAL of those AA filters on my shelf that were half price..it'll probably be a couple years till I finish with them .

Didn't Purolator use cardbaord endcaps on a few models for a while? My guess is that it's a Purolator...

As is usually the case, the base plate might answer this mystery.
