Here is some info I've compiled from LX and Mopar Information regarding spark plugs and what the come with from the factory if it can help you decide.

Here's a list of the stock plugs that come with each engine option found from 2008-2010 Manuals. 2005-2007 Manuals say "Refer to the Vehicle Emission Control Information label in the engine compartment." under the spark plug section.

2.7L - Champion Copper Plus + RE14MCC5 or RE14PMC5 or #470
3.5L - NGK Platinum ZFR5LP-13G or #7781
5.7L - Champion Copper REC14MCC4 or RE14MCC4 or #570
6.1L - NGK Platinum PLZTR5A-13 or #4498

Gaps are all .050 except 5.7L which is .043

Now on 2011-2012:

3.6L - RER8ZWYCB4 (Only cross reference I found so far was a plug that fits maybe a Kia Soul? RER8MC, RER8YC, RER8MC4 and Maybe a Champion 445 or 929 - I wouldn't quote me on this newer stuff)
5.7L - LZFR5C-11 or NGK #92174
6.4L - LZTR6AP11EG or NGK "V-Power" Copper #5306

All gapped at .043


[Updated] 2013-2014:

It appears the plug for a 2013 Charger RT (according to another Charger forum member's dealership) is a NGK LZFR5C11 or NGK #92174 as a carry-over from the 2011-2012 Models. It would be interesting to confirm what actually are pulled out of the latest V6 models and SRT8 models as well.

I got all the info from user manuals, If anyone finds conflicting info, I will adjust the material as such.

I've been searching for 30 minutes straight looking for plug gap info for my 6.1. Many belated thanks for this post.
