E3 worked for a while ....
I also tried the E3's ... did feel a difference, got a slight gain mpg.
But, had the same problem - cylinder3 fouled. Replaced the plugs with the OEM's I had removed and issue was resolved.
Overall don't think the E3's are as reliable as OEM's ... Just my opinion
Currently running OEM's ...

I'm looking to swap out the plugs also just because the rough idling drives me nuts. I've read a few posts that mention the factory installed plug gaps were off on some Jeeps, so I'm hoping a fresh batch of plugs will help.
Anyone have good results with NGK and which type did you go with (V/G/Laser/Iridium)?

Plugs is plugs if you ask me. Stay with the ones that came with your jeep as the engineers usually know best. If your 2009 jeep is running rough you probably should take it right back to the dealership and have them look into it, make them pay for new plugs if thats the problem, its still under warranty. They might even be able to flash the computer to take care of those kind of issues.
As for the quality of my american made jeep. I would put it up against any other vehicle in the same class anytime. This is my 6th new chrysler product and not one has ever let me down.

I just did a tune up last weekend. Here are my lessons....
I have an 07 with about 69k miles...
I purchased the double platnums from autozone for about 4/plug. I started taking the wires off and quickly realized the wires were damn near welded onto the plugs. At 69k miles, the plugs were actually in great shape showing NO WEAR. I replaced them anyways since the plugs were already purchased.
One of the wires was so stuck the metal connector stayed onto the plug as the boot broke free (and yes I did not pull from the wire. I pulled from the boot). Breaking that wire was the biggest pain in my ASS. You CANNOT find spark plug wires ANYWHERE besides at a stealership. Trust me, I called everywhere. Stealership wanted about 75 bucks. I had no choice.
Lesson: everyone pull those wires now and lube them. It will save you so much heartache
