NGK Platinum vs NGK Iridium? Worth it?

I have read on the net that iridium spark plugs can improve FE. Replacing worn spark plugs of any kind can improve FE. But will iridium spark plugs give better FE than platinum plugs? By how much? I think a set of 4 platinum plugs runs about $10. I think a set of the iridiums will run $30-$40. Are they worth the extra money?
