stay with new stock plugs, thats the best and only way for the 4.0, as far a wires go, i have heard that upgrading is not a bad idea. the 4.0 runs best with mopar stock plugs. i have the 4.7 HO, in my overland, they say that this one comes with platinum plugs and thats all that should be used.

I run the NGK spark plugs. When its time to replace wires, I normally go with a premium wire that has a spiral wound conductor. It transfers the spark better and suspresses noise. My preference is the MSD plug wire, either 8mm or 8.5mm wire. MSD makes a very nice wire and connector. I build my own for my customers who want the upgrade.
