Well, I are these the plugs everyone loves for the 4.7L? If so, do you gap
these guys like regular plugs. I heard they come pregapped. Is this true?
Also, the FSM do NOT use platinum plugs in the 4.7l. Is this due to the
weaker ignition? What is the downside to using the 4417's? I've heard they
work well, IMHO. All input is appreciated..
