so my dad is getting ready to change his spark plugs. (fyi, his truck is the same as the one in my sig) he went to ford and asked for the part number for his plugs. the plugs that ford told him to use are copper. he then went to KOI to see if he could get a better price there. he checked the plugs that they recommended and they were platinum....so what do you guys recommend?? i think he wants to stick with motorcraft. does anyone know a part number of what he should use??
