Standard Champion copper top - less than $2 ea. and the 4.0l LOVES them !
Autolite is a good second but don't waste your $ on fancy plugs. You will be disappointed in the performance.

Use what the factory recommends and nothing else. Newer vehicles have extremely finicky ignition systems. At least once every other week, i get to diagnose a misfire code on a backyard "mechanic"s car or truck that hes "just changed plugs and wires" on.
It may not show immediately, but using gimmicky quadruple hardened double uranium 6 tipped plutonium plugs is going to cost you in the long run.
Gm takes ac delco, ford = motorcraft, chryslers use champion, honda is ngk, so on so forth.

champion copper ones here. my old plugs (NGK) after 7000 miles went from a .035 gap to a .060 or more on an all the plugs, and one of tghe sleeves even broke and caused what sounded like a rod knock.

champion copper core, most likely will have a misfire if you put plat or irdium in there, copper the best conductor of electricity, the only reason y you run plat or iridium is so the car needs "less maintance" and if the plugs are difficult to change (ex. have to remove manifold for the back 3)
