Spark plug gap...help
I got my Denso Iridium IKH22's. Do I need to gap them? If so please let me know. Was planning on putting them in tonight. Be pissed if i have to pull them all back out to gap them. Thanks!

Never, Never install plugs, (even pregapped ones) without verifying the gap.
They can get rattled around in the box during shipping etc, never trust anything that critical to chance.

Normal procedure is to gap them closer for nitrous. Stock gap is .044 and I gap at .035 for nitrous with Copper NGK's. Not sure about the Iridiums.

I left all of my plugs at the stock gap for all my cylinders. I am running IKH20's (1 step colder) with 150 - 175 shot, no issues. Not that I recommend that at all. It depends on how much nitrous you are running. I think the stock gap is generally safe up to about 100 or 125 shot. I tend to be a little more risky with my car, but never once had issues with nitrous on my last three cars include my g35 (present car).
