MSD Spark Plugs for LS3

Just ordered a set of MSD plugs #37124.

The plugs come preset with .047 gap, but the default setting is .040.

Should the plugs be recalibrated to a 0.40 gap, or should they go in with the preset gap?

Read your owner's manual.

Yeah, I saw that. Then I saw the difference in the gap after purchasing the plugs.

I thought iridium plugs couldn't be calibrated because the tip is very fragile...
