what spark plugs do you run in your lt1?

I don't have an LT1 but I run AC Delco Iridium plugs in all of my GM vehicles. Took em out of my Camaro at 150k with 45k miles on them and they still looked almost new haha. No change in the gap or electrodes at all.

really, were you having problems with your car running or anything. i think running lean burns up plugs
