i have the v power ones on my 97 4 cylinder accord. they work fine. i was told not expect anything spectacular from the "iridium power" so i stayed with regular plugs. i did hear that a guy bought the bosche +4 platinum for his civic and blew his head gasket. this could have been a mistake that the guy made. i just dont want to risk it.(it may be a freak accident) furthermore, i stuck with similar stock plugs because im sorta cheap. (just look at my motto below my post)

does iridium make a diff?
