    NGK Iridium Gap Issue

    Regarding the gap for NGK Iridium's (p/n 7164) I just bought them and they are all gapped at 57. I've read other posts that said the gap s/b 60; another said the Iridiums are pregapped at 55.

    Should I regap them to 55 or 60, or should I just leave them alone?

    My engine is stock no headers and such, my mods are only an SLP MAF, SLP
    lid and a Magnaflow catback.

    I just got a set of Denso Iridiums and have the same question. I was always told that all iridiums are pre-gapped.

    Anywhere from 55-60 should be fine.

    They should be gapped @ .055 in a NA engine.

    I read .55 as being a 1/2 " gap.

    Be very careful if you gap them not to snap electrode.
