Which Spark Plugs Do You Use

[LoneWolf3574]

I'm just curious as to which spark plugs you guys use in your Ram's. I've been browsing this forum and other Hemi related forums and have found a general consensus that the Ma Mopar recommended copper plugs work the best. My son and I just changed the spark plugs on my truck and the old Champion 570 RE14MCC4 plugs we pulled out ranged .051-.059 with most being .051-.053.

So which spark plugs do you use in your Ram, why, and do you see any noticeable difference when you have used other types?

I'm using Champion 570 RE14MCC4 Copper Plus plugs since they are the recommended replacement plug and obviously at this point, I haven't used any other plugs. I am thinking about trying the NGK 5306 #LZTR4A11 V-Power the next time a spark plug change out comes due. It's still copper and I've had great luck with NGK in other vehicles in the past.

Don't ask me why but all the Dodge aka Ram and Dakota use Champions in them I guess its the nature of the beast.

Typically a gen3 hemi slightly modified does great with the NGK/ Champion plugs one grade colder. They generally grow .001" ever 2000 miles.

So you guys recommend copper plugs? no Iridiums?

Yes, do not put iridium in the 2006, it will not run right. Ask me how I know, lol...
