Champion or Autolite will work just fine, no need for expensive plugs, the only difference you'll feel is in the wallet.

With the 4.0 I have read a millions times, stick with copper plugs. One they are cheaper and two they perform better on these engines.

Make sure they are gaped correctly and you will be golden

I have the same engine in my laredo. Use Champion 4412 truck plugs if you can find them because they been discontinued but are still on the shelves of many parts stores.
