Does anyone know if the Iridium NGK is pre gap or you need to gap them. I was about to do it to the Sequoia this evening.
I read on the box, it indicated don't gap them, since the "needle" is thin and sensitive. So no gap needed.
But I think the regular NGK required gap like .030-,032 or something.
