I have in the past, they are a decent plug.
The only platinum plug I've seen serious issue with has been Bosch. That's more from the design than from being platinum. If you look at the center electrode it is TINY and prone to fouling.
Platinum is used as a wear surface, being a harder material, it resists wear compared to a normal plug. As far as function, it's the same, there is no magic properties in a platinum tipped plug other than increased wear resistance.

I liked the E3s myself.... and in the 4.7... oh no! No really I've had good luck with these. Old plugs still looked good, and mileage did go up, so who knows, but it makes me feel better.

 Use the factory plugs, all the other special super plugs don't do anything but cost more money! They won't hurt your engine and they won't give it more of anything!

They may actually work on a wj, but they made my zj run a little ill.

not to thread hack, but would new spark plugs help my ticking issue. it is intermittent and seems to be coming from either the plug or the coil pack thing on the plug, it is an 04 wj with the 4.0 i6. can't seem to track down a cause of the ticking, it all looks factory from what i can tell

I tried the E3 plugs a while back, and while my mileage did go up briefly, it only took a couple of days before I had misfires because the ignition coil couldn't supply the amount of power the plugs demanded. They create a larger spark and do it faster, but this results in more power being used. I have no doubt that they would be great in conjunction with a performance ignition coil on WJs or a completely aftermarket ignition system with ZJs, but for a stock setup, in my experience they were a complete disaster.

Usually my attitude, but for 20 cents more per plug, I'll take the platinum right now just so they'll be good for and maintain an accurate gap longer than copper.
