What type of spark plug do you prefer

What choice of plugs do you guys usually go with?

ask mean05. I cant remember exactly what he had me buy. I know they are NGK. He told me at least 3 good reasons to run them. Sold me on them

wow this is a new one !ngk tr6 .

TR55 on a stock engine, TR6 on boosted or mild nitrous setups

old setup on motor was the NGK TR55 and with the bottle NGK TR6

AC Delco 41-985 Iridium.

I did a search and it looks like the TR55 is what im going to go with. Should I go with the Iridium or not?

No, the regular ones work just fine. Iridium is much more expensive. I had iridium plugs once, spent $80 on the set. I now have regular ones that cost $17 for a set and noticed absolutely no difference.
