A colder plug is not going to cure a lean condition. A cooler plug is used with N.O.S. or forced induction (turbo/supercharger) to keep detonation down. It will not fix a lean condition.
A good tune with a slightly richer a/f ratio would be a safer bet. Heck, a power wire may richen it enough.

What intake, headers & tuner you got? I'm running a K&N, Pacesetter Long Tubes and a Superchips and my plugs look perfect with 22k on them. I had the original set in for 11k after I installed my long tubes and to be honest, had I not already bought 16 Champions, I would have let them go past 30k, they looked fine and the gap was still perfect.
That's why I don't let anybody else touch my truck and do all my own work, I can see for myself exactly what's going on when I change something...

Yep, that's what I was gonna say. I'd bet they were burning white before the headers went in. The Hemi don't like iridiums or platinums, but loves good old cheap copper plugs...

hey guys there is nothing short of changing stock stuff that will give any change in HP or range of performance. Air flow and exhaust flow will be the only things that will change anything like that. The stock computer will always bring anything u change back to 14.7 to 1 fuel ratio. So if u make s spark plug work harder to fire the burn time will simply be increased from the coil pack. The computer has one goal and that's to have the best burn efficiency possible a 14.7 to 1 fuel mix. Unless u change the PCM programing just about any mods are a waste of money.
