The old guys too. My 1st set where in March 07, gapped at .038 and later at .035. Never had an issue or breakage from an Iridium regap.
I have never heard of being extra careful on iridium plugs.Im careful on all plugs when I gap them anyways.Someone else on another forum said Do NOT gap iridiums at all.I threw up a BS flag..
I have never heard of anyone breaking them, either...Like Scott and JMatt said just be careful and you will be fine!
