Re: DIY: Hemi 5.7L Spark Plug Change

I remember doing this on my '05 Magnum R/T. A guy on the LX forums did a similar write up. It made life so easy from me and I really loved doing it. I'm at 32,000K now so might be time to dive in. Thank you for the write up.

Re: DIY: Hemi 5.7L Spark Plug Change

great write up and it's a job I have always done on my previous cars.

My dealer has a price list, for a Hemi, they want $250 to change plugs!!!

Re: DIY: Hemi 5.7L Spark Plug Change

Manual says to change plugs at 32K miles or 24 months, whichever occurs first. At 24 months, I will have around 20K miles. How important is it to change plugs at 24 months with less than 32K miles? If I wait until I get the miles, will this impact the warranty?

Re: DIY: Hemi 5.7L Spark Plug Change

Just changed mine at 26,140 and 15 months old. Butt dyno like the new plugs.
Thanks for the write up.
How do you reset the ECU? I removed the + terminal in the engine bay for over 5 mins.

Oh, and I am still getting the rough idle ~600 rpm. Any thoughts?

Re: DIY: Hemi 5.7L Spark Plug Change

In this post it says to tighten spark plugs to 12-14 lbs but on wk2 jeeps, it says 18.5-22 lbs. Which is accurate?

Just got off the phone with the dealer to double check and was told 13 ft/lbs +/- 2 so I believe my numbers are good. I swear I also found it in the user manual originally but now can't seem to find it!?

Can anyone else confirm 100%?

I didn't see any mention of using anti seize on the plug threads. Anti seize is essential in preventing galling of the threads in aluminum heads in the future and possibly having to perform thread repairs on the heads.

Re: DIY: Hemi 5.7L Spark Plug Change

Never used anti seize. Always used Champion plugs which have a treated shell and threads.

Re: DIY: Hemi 5.7L Spark Plug Change

Who makes the MOPAR plugs? What is the specific model number? I want to say with my '05 they were made by Autolite...

Re: DIY: Hemi 5.7L Spark Plug Change

Just tackled this job on my Jeep, have to say, it was a piece of cake. Also, someone needs to teach the guys that put the OEM plugs that 12-14 lbs is not the same as 120-140 pounds. I had one plug that I needed to bust out the breaker bar to get it out.

I went with Champion plugs, because they were on sale AND has a rebate. Win-win.

Overall an easy job. The driver's side is a little more difficult (but still cake) and the passenger side is literally the easiest set of plugs EVER. Coming form big transverse V6s stuffed into cramped engine bays, there was tons of room everywhere to work.

Not something I'll mind doing again in 30k miles, especially given how inexpensive it is to do the job.

Re: DIY: Hemi 5.7L Spark Plug Change

I just replaced the plugs on my 12 limited with the V-8 at 31000 mi.. has anyone else noticed that the plugs showed No need to be changed the gap was right on .43 no sign of over heating (porcelain discoloration) I opted for the lifetime unlimited mi warranty SO i really have no choice but to replace them
