Replace Ignition Coil Boots with Spark Plugs?
I'm replacing spark plugs on my 2014 Charger 5.7 R/T (approaching 100k miles).
Is it necessary to also replace the ignition coils and/or boots?

Not if they are still in good shape and working... A little dielectric grease in the end of the coil boot, reinstall and send it on its way...
Also, One thing to check in your service manual... Check the recommended replacement interval for the spark plugs, I think 100,000 miles is a little far out...

Thanks for that!
And yes, according to service manual it is 100k miles. Maybe because they're iridium plugs.
