The 2014 is 100k before plug change. Most modern engines are over 75k, I cannot understand what Dodge engineering did to make the 2011-20013 need plugs that fast.
They take after Kia's scheduled maintenance service now which is a weird parallel to be able to draw. . .but hey if it keeps em on running then why not.
The wife has a 2007 300C 5.7L that has 78,500 miles on the odometer. I "cleaned" the plugs at 72,000 miles and the gap was at .054". I filed and regaped them to .043" and screwed them back into the engine. There was no change in performance or mileage.

Waaaaaay back when, in HS auto shop we used to clean our plugs too. It was like a mini sand blaster with glass beads I believe that you would push the plug into this rubber fitting, hold them in and turn it on. Wonder if those are still available. Plugs looked like new, just regap and install! It was great when you fouled a plug or two when changing jets and such in the carb or from street racing. A lot cheaper too( free
This question was asked over and over on another forum for trucks way back. I bought my 2003 2500 Ram (1st year the HEMI came back) and it was a big topic then. According to the Internet Dodge did it for emissions to meet a certain ppm at the 100k mile mark. This is all based on forum lawyers so take it for what's it worth.

Yup BadBen, that is exactly what I have screwed onto my garage wall and it works just great. Hook it up to the compressor and let it buck! Saved me a ton of $$ over the years.
