Well, I hadn't read this thread for a while. All I know is I put in a new set of Autolite double platinums and wires. They were gapped at a tight .060 out of the box and I had no reason to change that since I had no knowledge of this bullitin. That's why I asked the question.
How long ago was that? I just looked at an Autolight spark plug application book a few days ago, and it showed all their plugs at 0.040" gap in the book. Maybe you got some old stock (?).
If you want to look at Autolite's application catalog on-line, go here and look up your car. I just looked for a 2002 Z06, and they show all their plugs gapped at 0.040".
