You are the man...which is right?
Here is what NKG said on there web site: Iridium IX TR55IX 7164 .060
(This NKG tutorial video goes on to show exactly "how to gap a iridium plug" and "what tool to do it with")

The link that follows goes on to say and I quote:
"While it is a popular misconception that plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for."

Please correct me, if I am "out of context" on "Iridium" glugs not being pre-gapped for individual cars but it sounds like the manufacturer has some different wisdom to share, than the mainstream wisdom, here. I think this "issue" shrouds these plugs in mystery and accounts for some (occassionally) radical opinions on their use. I would like to see this issue clarified here, if possible. All opinions welcome. Thanks.
