Am I going to have any problems running the ngk 4091(R5671A-7) non projected non resistor type plugs in my 07 Ram? I'm ready to spray nitrous and the plugs are my last step, but I'm worried about RFI on my electrical system. Some say they run them on modern vehicles no problem and some say stay away.

Well the closest plug I could find that are non projected with a resistor are BR7EF and B8EFS. Only thing is the "reach" is slightly different. My heads calls for a .750 and these are .708. Not sure if .040 is a lot when it comes to the plug in the combustion chamber but it's the closest I could find.
