Did you have a problem with the iridums?

I just installed a set on my boosted car yesterday, haven't got a chance to run the car yet.

No problems at all running iridium. Copper works fine too but you will be changing them out much more often.And I personally hate changing plugs especially the back one on the passenger side.
