Oil Filters????

MoPars and Fords (To a point) have the same filter dimention needs. I get greif (From the stupid) about useing a ford filter. Though it's a FRAM brand, the PH8 screw right on without problems.
The different numbers are for in car fitment/ capacity etc...

Other filter differences are metal insides or not, paper filters or not, pressure relief valves or not, filtering abilty...........
