I would re torque to the correct specs for these plugs into aluminum heads!

Re: DIY: Hemi 5.7L Spark Plug Change

From what I have read, it is possible to throw codes and the 5.7s don't like anything but the copper top Plus when you are changing the plugs every 30000mi do you want to spend that amount ? what are you trying to get out of them plugs ? if its more HP go with CAI or the tuner

I know about the CAI and the tuner and if those plugs could add more power I'll get them ,too
Wherever there's a little chance for adding more horses I'll always be considering it even if it's an addition of a little pony.:-)

Re: DIY: Hemi 5.7L Spark Plug Change

Not sure if they make a Pro-Charger for the 5.7 WK2 but that would give you 130+ HP. wondering why you did not get the SRT8 ? That would give you HP.
IMO you should start a Thread and ask advice. because this could go on for awile and Hi-Jack this thread and I know you were just asking about the plugs

First of all no Hi-Jacking was intended ;-)
And I didn't get the SRT 8 for the love of the offroading , I don't see any SRT 8 does that. And there are many super and pro chargers for the 5.7 but the problem always has been the lack of tuners especially for our WK2s. So as you know I was just asking about the plugs :-)

The zinc plated threads on the OEM NGK plugs I removed, that were less than two years old, had already begun to corrode in the aluminum cylinder heads!

NGK's illustration of a novice installer, not using a torque wrench, making novice mistakes when installing sparkplugs shouldn't negate the use on anti seize when installing 100k mile service life plugs. Those plugs look like they were over torqued by a magnitude of three or four beyond the recommended 18~25FtLbs! You'll wish you used a little anti seize if you have to make that next plug change! Trust me on that!

^^ I think you will probably be fine with antiseize, I'm not here to get in p contest, but if NGK says you shouldn't do the antiseize, I won't. That PDF is enlightening. In my experience with antiseize, it is good for a year or 2 (in a non-high temp location) but it too can dry out, and who knows, make things worse?? NGK has a strong vested interest in not ruining heads for their customers. The Ir plug info (and OP post) is awesome. I can't find the NGK's online, but Bosch has plugs for $7 that are listed by O'Reilley's as for the Jeep Hemi, anyone use these yet?

Re: DIY: Hemi 5.7L Spark Plug Change

A note for those in Canada looking to do this job, the default go to guys (can tire) no longer stock basic champion copper plugs, at my location at least. Their options are e3 at $15each or platinum at $11 each. They wouldn't even order them in!!

However, Napa were quite happy to supply 16 at $3.49 each, saving a significant $120 on the platinums.

Re: DIY: Hemi 5.7L Spark Plug Change

I am ready for my Second Plug change, I ordered Mine for the second time on the Bay $61 about $3.80 each shipped and they are the Mopar plugs.. I have the Maxi care Life time warranty and IF something goes south withe the Engine the Last thing that I want is to get in a situation that they will not repair/ replace because I did not use the OME

You shouldn't have a problem w/ the new Mopar NGK Iridium plugs, they are OEM for all 2014+ 5.7L Hemi's; & can be used in all previous 5.7L Hemi's.

Mopar # SP-143877AA MSRP $17.25 (They come pre-gapped @ .044")

Just a better quality longer life OEM NGK 100K mi plug vs. the OEM 30K mi copper ones
