    indexing plugs

    I am a little confused on this and have read its worth 20 more rpm,

    from what i understand you put different amount of washers on each plug so that it will have the J hook facing your exhaust manifold?

    i dont kno if i am right or completely wrong so any help would be great.thanks.

    This is correct. You have to use indexing washers.

    Actually you use different size washers available at Yes the open side of the electrode faces the exhaust port.
