Iridium Spark plugs

Has anyone tried the NGK CR8EIX iridium sparkplugs? Is there any advantage to using these over the CR8E plug. I realize they are more costly, are they worth it?

Over the last couple of years this topic comes and goes. From reading most of them, I would say no, the piece is not going to yeild the performance or dependibility from fouling.....for the cost.

Proper jetting is the key to performance and dependibility.

For what it's worth, the highest marks go to Nippon Denso's Hot-U's and the Splitfires.

I have one of those NGK CR8EEGVXQPYDJT??? wonder plugs and can't bring myself to using it, to damn expensive :)
