  A:

  Engines of 4.7L require copper -core ground -electrode plugs usually matched to originals which may be a cause of pre -ignition. Since plugs are hand-started to avoid cross-threading and dropping, the torque applied to the 3.7/4.7L is 27 Nm (20 ft.lbs) and the critical 5.7L to ~18 Nm (13 ft.lbs) (no O-ring). O-rings in coils should be lubricated, replaced, and visually inspected.
