i have ngk 5306 in my commander, thats 1 heat range hotter. i think it idles nicer and has better throttle response. i think it runs better with them than campions. im putting in some ngk 4306 in my rt this weekend, i will follow up with ya.

i havent come to the point where my plugs need changing yet in my 2010,but i can say this,i have just put ngk iridium plugs in my 73 440 challenger and i am very pleased with them so far.i spoke with a ngk factory rep at a sales meeting a while back and he gave me some literature that was very good explaining heat ranges and so forth.i had some trouble finding a good heat range for my fickle 440 and these iridium plugs have been the best so far over champion,autolite,ac platinums and even bosch.

those plugs are for a tapered seat, the plugs that came out of my 2010 rt are gasket seat. we have some false advertising out there beware!!!
