I believe the Hemi's have platinum plugs installed from the factory...thus the 100K change interval.
No need to change out unless you have added a supercharger.

All kidding aside, modern ignition systems a rarely the weak link. Going with a colder plug if you had forced induction would be one thing but your plugs are fine unless they are worn out then another set of stock plugs will be the way to go.

The 2014+ 100k plug has an Iraduim tip. they are an upgrade to the 2011-2013 Hemi's
