Irridium runs cooler, I beleive. They are a lillte pricier, but worth it from all I have read.

 

neone else have ne ideas about this?

 

thought the HKS Iridium plugs might give me something over the NGK Platinum spark plugs, nothing. I know spark plugs per say are not performance gainers so I was an idiot to try them anyway. At the very least they may last longer than stock, but will go pack to the good ol platinums.

The only exception to this may be if your moded to hell then maybe, maybe these would be a benifit if not for performance at least endurance
Heres a URL for more info.
