Anyone using Iridium Spark Plugs?

[V6UnderPressure]

Just curious. And are they made for our cars? I was reading a few articles and these are supposed to be the innovation to stay cool. They are ideal for turbo cars. I am just curious if they make them for buicks. And if they do, what gap to run em at.

I dont know if they are made for Buicks yet or not.

The only time I have seen them necessary is when you have very big turbos that are basically blowing out the spark in high boost situations.

They are not cheap but I have read somewhere that Ken Duttweiler used them on a drag motor with twin turbos ( I think ) and they worked really well for him.
