    Has anyone used a plug other than the Champion A6G called for in the manual and had noticibly better performance? What did you use?

    I am assuming your asking about the 348? I sold my car a few years ago and the records went with it. You call any parts place and they would know. Regards, Vern.

    Another vote for NGK DR8EIX. Idle is noticably smoother, though one of the plugs I replaced had a damaged terminal which may have had more to do with it.

    Denso do an iridium plug with an even smaller electrode, but they were over double the price of the NGK's so I didn't bother trying them.

    "Should I gap my Iridium Plugs?
    The manufacturers say NO.
    This is because most people do not know how to properly gap a spark plug, and the center electrodes on the ultra-fine iridium can easily snap if mishandled. There is no warranty for snapped center electrodes. The manufacturers say an iridium spark plug will run so much better than a traditional plug, even if it is not gapped for that motor, that they would prefer you just leave it rather than risk snapping the center electrode "

    NGK calls for a 0.25 gap...should you gap the iridiums or not? -- clubnet says don't touch 'em

    Do not bother to gap the plug. There is no need to do so anymore. It should be set right when they package them at the factory, so dont bother. Just throw them in. :)

    DO NOT change the gap on Iridiums...the tips are too fragile, and you risk damaging them...it says so right on the box they come in!
