After reading the forums, I purchased AutoLite 985s. I was going to gap them and do the install along with a bunch of other things, but I'm moving (tools packed) and so I had my mechanic do it.
I brought him the plugs and other things only to find out that he did not install the 985s saying that they werent the right ones and that Jeep 4.0s dont really use AutoLites.
Instead, he installed Champion Platinums (not sure of the number yet). I have the AutoLites still.
Are the Champions okay? What's the diff between the AutoLites?
The Jeep runs fine as far as I know.
