Since I saw Ford Motorcraft get pounded in the Ground for being so bad to the point, Iam not sure I want to even use them anymore. I was curious does anybody know the effeciency rating on the black Mopar filters. When I do a search, All I get is the older grey filters that Fram used to make for Dodge. The new Black ones are defienetly Purolators and they are alot heavier but are they as good as the Purolator Classic premium filters. i would hope so, but the Mtorcraft ratings freaked me out.
