    Comments about Autolite Platinum Spark Plug:

    Better and longer life than copper core plugs at a better price than the multi-platinum, iridium, or split-fire style gimmicky plugs.

        Initial suggested settings for spark plug gaps are: Single plug : 0.028 - 0.032", Dual plug : 0.025 - 0.030".
