Very strange per the sticker, correct plugs are p/n SP000ZFR5N, Gap: 0.035. I would probably pull one of the existing plugs and see what is in there.

Re: 04 wj mpg

LOL. I am just curious now. I looked at the sticker again and it's from a 4.7. Should there be a sticker with the vin under the hood?
