I have a cold air intake and superchips flashpaq. I have a slight oil-buring issue and just changed an oily PCV valve. Plugs are a bit burnt, but not black. What do y'all recommend with a factory ignition? I don't want to start changing everything under the hood for the sake of reliability and longevity... I have owned 4 Jeeps and modified them all, but this is my first JK and I plan to keep it under 35s and still get decent power and gas mileage. Thanks!

Your Jeep will run best on the Stock O.E. Spark Plugs... Truth..!

X2 on OEM plugs. No need to get fancy with plugs until you start playing with forced induction or higher HP applications. Save your money!

Buddy of mine put the e3's in his 08 JKR. It ran horrible. Was very rough idling and when he was driving and hit WOT it would hesitate a lot. He also put on performance wires and coil pack. He went back to stock pack and plugs and kept the performance wires on and ran good and got a little better mgp. The e3's were designed for high performance vehicles, muscle, tuners, and race cars. Another buddy put them in his RSX type S and had quite a bit of other performance mods on it and the e3's worked great. Horrible for our Jeeps though.
