Changing my spark plugs tomorrow. Pulstar iridium pulse plug.

I was told to not change the gap on iridiums. Is this correct?

If not, what is the gap on an '06?

Iridium plugs have extremely fragile tips. It is very easy to break that tip! I would only lay that feeler gauge near to the tip to visually check it looks right, not placing it into the gap. You will break it if you do. Notice that the tips are surrounded by a protective tube from the factory.

Check the NO WARRANTY part of this thread. Apparently related to sparkplugs.com, one of our sponsors. I bought my plugs from them, and found the gaps set fine.

I did mine at 35k and they were kinda gold rainbow. Nothing serious. I replace with original ones from Nissan. Because my friend used Bosch double tip and got issues.

Most factory plugs don't need to be changed until at least 100k.

Yeah I called the dealership today talk to the sales rep. She said it all depends sometimes 50,000, 40,000, and she said even at 30. Lol. Then I called the parts guy, He said 100,000. Everyone's trying to make a buck today. Thanks.
