Not sure plugs ever made much difference except how they hold up over time on cars, never bought into the deal. What I do know, is that my 05 Ram Quad 4.7 was a good running truck, it lacks bottom end guts, and with 35 inch tires, you are likely below the engines power band, unless you changed the gears to above 3.91s.

Platinum plugs are NOT for every car- change them-


dodge trucks run the best on the stock champion plugs.
