Spark plug change - 2019 Ram 1500 w/ 5.7

[Mr.Grid]

Finally got around to changing them this week at 103K miles. The spark plug tool mentioned worked great for all but two plugs. No way to get it to fit the two right near the brake booster. I had to put a spark plug socket in the hole, then attach a short extension, then a swivel adapter, and then the ratchet. I did those two and the back two on the drivers side first, and those 4 took about 2 hours and lots of cuts and scrapes. Called it a day after those 4. Did the other 12 today in about 2 hours. The other 4 on the drivers side were still a pain due to hoses, lines, and close wrapped wire bundles. All 8 on the passenger side were super easy in comparison.

Changed the PCV valve and cabin air filter today too. Glad this is finally done.

If you still have those spark plugs you replaced, can you put a feeler gauge to them and report the gap now that they have 103K miles of use on them? TIA

Going to be doing my spark plugs .. I'm going to be ordering them from Rock auto.. when i go to check out there is a disclaimer that says : "Manufacturers recommend replacing spark plug/coil on plug boots when replacing spark plugs" ... Is this true? or can i just re-use what I'm currently running. has anyone replaced them?

I've never replaced them or the coils unless there was an issue. Just take your time pulling the coil off, so you don't mess a boot up.

Rarely is there an issue with the boots. Replaced many spark plugs on the 5.7/6.4 hemi-I never recommend them unless there is an issue.

Ya just give em a twist as your pulling I don’t change em unless I have to then you can always shoot to the parts store

I just replaced my spark plugs. It wasn't really horribly bad on the drivers side. I think the worse part was getting the wiring harness out of the way so i could unplug the 1st connector from the coil pack on the #1 cylinder. passenger side was a breeze
