    Rated 5 out of 5 by from I can't believe the difference these plugs make. I can feel the difference in power these plugs make over the other (Autolite) plugs. I have used E3 in the past, but the new style is much better. I am putting these in all my pickups.

    Asked by: dansodomin
    This will depend on the cylinder head you are using. many aluminum heads use a gasket type flat seat spark plug, while many cast iron heads use this tapered seat style plug.
