Guys, I have a set of Denso Iridiums w/ about 1,843 miles on them. I moved to one stage colder due to the high boost levels that I'm running. Plugs are in great shape and for run about $28 each plug locally and about $55-60 shipped on ebay. Granted the NGK's go for about $40 shipped on ebay as well, so I'm selling them for $25. Let me know. You really can't go wrong.
