I agree! The gaps look inconsistent across those plugs . . . I hope you gapped your new plugs??

Re: DIY: Hemi 5.7L Spark Plug Change

A heads up, my 2014 Summit V8 had Iridiums and I purchased Iriduims from the dealer.
I gather that prior models have copper plugs.
Great DIY write up and very easy to do compared to my old 2000 JGC V8 and my old 2008 Toyota 4Runner.

Mine is at 52,000+ on its original plugs. I hope tthey last as long as yours has. To help, I give it an "Italian tune-up"a time or two a week and I just added a 20oz can of Techron Total System Cleaner to the tank. I also try to fill with the new Shell gas each time too.

Re: DIY: Hemi 5.7L Spark Plug Change

Mine is running so good I am afraid to touch it. I am going to look up some good plugs tomorrow and probably put them in this weekend.
The dealer has managed to screw up both recalls I had done and now they want to do the fuel pump relay. I'm not sure I even want them touching it again.

You know the old saying. If it ain't broke, don't fix it. Remember, dealers get paid for all this work. If not by you, then by Chrysler. Their interest is the $$$$$$$. Always the $$$$$$$.

Re: DIY: Hemi 5.7L Spark Plug Change

I'm getting ready to change mine over to the Evans waterless coolant so now would be a good time to at least pull one or two out and look at them. Dealers around here want $400 or so. Not gonna happen.!!!!

Re: DIY: Hemi 5.7L Spark Plug Change

Everyone here is talking about iridium and copper plugs but nobody mentioned platinum. I changed my plugs to Champion Platinum Power at 32,000 and am almost at 76000. The V8 is still performing the same way as before I changed them out. I'm getting about 20 - 22 MPG freeway and about 13 - 16 in the city.

I heard those can go 100,000 miles but was planning on changing mine when my odometer hit 96,000 or so. Should I wait to change the plugs out or should I just stick with the 32,000 mile schedule and just swap them now? Thoughts? If I swap them out now I'm just buying regular copper tops as there's no advantage of buying anything else then.

Re: DIY: Hemi 5.7L Spark Plug Change

I'm going to try and change mine this weekend if my son is not too busy. At 68,000 on the original plugs, it seems to be doing very well. I have noticed a very small stumble at start up mainly because I have the Corsa cat back exhaust and can actually hear it run. And at about 4500 rpm or so, there is a little bit of a miss. I am anxious to see if the new plugs get rid of that. Other than the evap purge valve going bad, this one has run flawlessly since it had 1.2 miles on it the day I drove it home. I am more pleased with this vehicle I think than anything I have ever owned.

Re: DIY: Hemi 5.7L Spark Plug Change

Changed all 16 today. Used Autolite double platinum. Old ones at 68,400 miles had just burnt about .002 open. I can tell a difference in the way it runs now.

Not too bad for 68,450 miles.
