Thoughts on Iridium Plugs

Anyone using these in the LT1 Forced Induction world? Your thoughts? Experiences? Ideas?

Thanks

Throughts; expensive. I think they work well on stock ignition cars.

They would be superiour to platinum plugs, but for a FI app not as good as copper (they are still more prone to hotspotting, etc. as they don't conduct heat away as well.

Chris.. for coppers do you mean regular spark plugs?

Thanks

Can't find it now, but on the NGK website they did mention these plugs are not recommended for forced induction applications. Don't remember that they gave a reason...
