howdy........i now have over 30,000 miles on my 07 dodge nitro slt and according to the maintenance record book, i am suppose to change out the spark plugs. why aren't these 100,000 mile spark plugs like some vehicles have? has anyone changed out theirs yet? if so, what kind did you put in. any suggestions on "the best" spark plug would be a plus for me. thanks!
