NGK V-Powers (V-Grooves). Stock # 6987 gapped at .040 I use them for my Jeep and my mother's Jeep. Never had a problem with them. I change them in both Jeeps every 6 months regardless of mileage. It gives me an excuse to go out and play.

It is time for new plugs. Any suggestions on the best spark plug to buy for the 04 Libby 3.7L ? Thanks |

I just used the search function with that same question. There are tons of opinions on this subject to say the least. Based on my notes, don't spend alot of $$ on fancy plugs and just change them every 20-25k and all will be well. I was going to just use the NGK V's but will probably go with the Autolite Platinum for $0.19 more each. Jake |

Autolite double platinum are a good choice. I have them in my KJ now. |

OK, I'm changing my choice and going with the NGK's.
Since buying my used 04 Libby a few months ago I've found out how over the last 25 years I missed doing my own maintenance/mods on a vehicle. It surely has made me feel much younger after the toll of all those years in the concrete jungle. Jake |

Jake Autolight double platinums or bosch platinums(single,not the +2 or +4 junk) are really good plugs.If you want the best plugs get Denso Iriduim plugs,they are awesome for high compression and high HP apps. |

I agree with you about the gap. I replaced mine after 18,000 kms (11,250 miles) and they were all about .045, except one which was .050 When I did my Mother's Jeep tonight, all hers were about .050 Her mileage is 31,000 kms or about 20,000 miles. I have read where you recommend the Autolite Platinums. Just doing some quick research, they look interesting. I will give them a try when I do my next plug change. Is there any benefit in going to the Autolite Double Platinums over the single Platinums if they get changed out every 6 months? I am not married to 6 month plug changes either, it is just a reason to work on my Jeep.

Until I got my Jeep I really did not know how much I missed messing around with mechanical things and playing with tools. It brings back great memories of hanging out at the airport and working on airplanes when I was a teenager. |

I had mine replaced at 30K with NGK v-powers, gapped to .040 as well!!! I will be attempting to do it myself this next time, in <7K miles. When doing them (I know I have seen the write-up on it but just want to make sure), do I have to get a torque wrench? If I do, what do I need and what torque do you torque them too? If the wrench is too much, I can just have one of the shops around town do it, like I did last time, and it was only $100, but I know they did it righ too! ~Thanks~ |

Mine came with NGK Double Platinums, rated at 90,000 miles. I'm at 52,000 and never changed them. The tips look as good as new, never had a misfire and my mileage hasn't dropped. I've never checked the gap on them, but so long as everything keeps running good, I'm not messing with them. |

Every time you rotate your tires you'll need one, for example. I think plugs are about 20 ft lbs, IIRC. Not a lot, for sure. I don't use a torque wrench on plugs, though, just snug them up. |

Turn the ratchet until it's no longer easy to turn with just one hand. Only use your wrist to turn the socket, do not use your arm. |
