Fram Tough Guard with Filter Mag cut open

[@philipfarnam6013]

Have used Filter Mags for years. They work...period. Except for purchase price, no downside to them. My UOA iron measurements lowest I've seen in any UOA's from anybody. (Purolator Boss; Pennzoil Ultra; 6,000 intervals)

I definitely like to try to remove any contaminants in the oil. I usually run a higher quality filter.
