Spark plug help fast! Hey guys I'm in the middle of the LT install and pressed for time (getting dyno tuned tomorrow). I wasn't planning on doing plugs, but I figured why not. The car had Denso Iridiums and was running great, but I can't find them anywhere. Are Ac Delco Iridiums good to use? I know they cost $7 each but I don't care as long as they are good plugs and will last me a while. And what should they be gapped at? Thanks guys.

I just put a set of NGK TR-55IX's (iridium) in my car and noticed no difference from the NGK TR-55's, runs great with either.

most people get the ngk v-power's which is a copper plug, but ngk also sells platinum that runs around the same price as the iridiums. Myself, i got the ac delco just to keep everything the american muscle way.
