Copper plugs, as everyone else is about to tell you, are what you need for a 4.0. Assuming that is what you have. Champions Pre 97, NGK 97+.

yes I have a 98 4.0
the e3 has a copper core, and nickel tip
champion copper: copper nickel alloy core and tip
ngk has nickel tip and core...
what I want to know is if this plug truly would help reduce fuel and add more power
