Yours will be different in that mine is distributorless, but the plug numbers are the same for the 4.0. Champion or Bosch is a matter of personal preference. I've always used the Bosch Platinums since they are generally good for 60k+ miles, but the plugs in the 4.0 are super easy to get to and changing them could be done in 15 min. You may read that "platinum plugs are bad for a Jeep". I have found absolutely ZERO credible evidence of this. To each their own.
