Went to Lowe's today, and while there grabbed a couple filters to cut open. This is a Blue Mountain BMJ4459. Same as Fram PH3593 or AC PF1127 or Purulator L14459.
Cost me all of 36 cents.
I cut a Fram that I will post in another thread.
All the stuff
Some excess glue, but no tears
Side with tight pleats
Side with wide pleats
Diagonal slots on the inner core
