I know many people must be coming up on their 30k mark for the V8 5.7L. Im only at 18k so I have quite a ways to go but want to educate others and find out myself. on wk2jeeps.com and the owners manual it seems the 2011 OEM calls for 16;

NGK ZFR5C11G

Now sparkplugs.com and other sites list an OE replacement as;


NGK ZFR5C11 and a Champion REC12MCC4



What's the difference between them all? I realize the NGK is the matter of a letter "g" but I assume it means something. Havent seen them online with the "g" only listed as zfr5c11. They are OEM/ Copper plugs, nothing special between all three however.. Champion plug is about half the price of the NGK plug.
