I run the autolite 985s(cheap plugs) and have had no problems for the last 4 years. I have never been a big fan so called performance plugs.

Copper only. Many, many people have issues with the basic jeep engines vs the fancy complicated spark plugs.

Miss Amy's sensibilities and the language filter prevent me from telling you what I really think about you.

I was not impressed with the E-3s, and have gone back to the copper plugs that work well.

There are a lot of gimmics out there and this is just one of the latest.
Not to long ago scam artists were selling small 12v fans and marketing them as "electric turbochargers" nothing more than a scam.
Your rig will respond well to a tune up using quality stock replacement parts.

I used to buy the standard Autolite 985 plugs from Wal-Mart and I had no issues with using them. Then the local Wal-Mart stopped carrying them, and they only stocked the Autolite AP985 "Platinum" plug. They cost about $4-$5 for a 2-pack.

I started using them in all 3 of our 4.0L Jeeps with excellent results.

There is no situation that cannot be improved with a small but well-placed explosive.

Standard Autolite 985's all the way. For the price difference for the fancy platinum or titanium or irridium you will not see any difference versus standard Autolites.
