I just put in some $2 copper plugs, and she idled like the day I drove her off the lot.
Well, after I re-attached the passenger side plug wire that I'd forgotten to push back on...
Thanks again.

I have 53,xxx miles now on my 2012 KK and am a little shocked and embarrassed to learn that I should have replaced them 20k miles ago. My last few vehicles were Japanese, and I had thought copper plugs had been rendered obsolete alongside the distributor cap. Just bought the E3s from O'Reilly. Any success (or failure) stories? |

Return the E3's and buy the stock plugs, your Jeep will thank you. http://www.carsdirect.com/car-repair/copper-spark-plugs-vs-iridium-and-platinum-understand-for-top-performance There is nothing obsolete about copper plugs |

X2................. Don't walk back run back and get the correct plugs.Plus those e3 plugs are pure snake oil,only good at draining your bank account.Copper plugs give the hottest spark and there so easy to change on a 3.7 doing them every 30k is a breeze and cheap using the correct plugs. |

I'm sure there is one on here (honestly havent searched yet) but since the topic is up ill ask. Just did the plugs in my toyota and desperately need them on the KK. Is there any write up on here to do them? I was able to find a YouTube video for my toyota but none for the KK.

Man, it's super easy. The 3 on the passenger side are accessed by just removing the boot over the plug. You'll just need a plug socket and a socket extension. I had a 12", which is nice to get your wrench up above everything. The driver side is accessed by removing the 10mm bolts holding the 3 ignition coils in place over the plug. That's it! |

Don't expect the bolt on the plugs on the driver side to come out. you loosen it up as much as you can and then yank on the ignition coil. Theres a little ring on the bolt that holds it in, once its loose pulling on it will make the coil come out. Make sure the engine is cold too.. Reaching the plugs on the passenger side can get pretty hot lol. It does help to remove the air box as well. |

The driver's side threw me off at first until I just tried giving the coil assembly a quick tug. LKWJeeper wrote: It does help to remove the air box as well. Good tip, but with a ratchet extension, I did not find it necessary to remove. |

Ok. I bought these today. Said they were OEM. Are these the NGK's that you guys refer to? Only listed "copper" ones were the Autolight's.   2011 Liberty Sport KC slim LR 130w on bumper, Cobra 78, firestik, Dunlop Fierce Attitude. |

Looks like it to me. Mine came in a Mopar box. Someone else might be able to confirm, but if they said they were stock OEM and copper, they're probably right. Gap to .043. |

O'Reilly says those are nickel, apparently: http://www.oreillyauto.com/site/c/searc ... &brand=NGK Edit: According to the guys here, your NGK V Power is the OEM Plug: http://www.jeepforum.com/forum/f28/3-7l ... ndex2.html |
