Spark plug question

I'm currently running the 3347 BR7EF. Has anyone ever run iridium plugs and had any luck with a modified setup?

Your car came from the factory with a set of NGK Iridium Plugs, and most people on the forum run them modified. Most move from the stock TR6IX to the TR7IX.

.40 is standard, but depends on your tune. I personally would not go under .34, but some are down into the .2x range which is a race tune.

Thanks. Tuner and the shop he works at haven't suggest the iridium and just use the BR7EFs.
