    3923 - Autolite Copper Core Spark Plugs is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Works perfectly in AFR heads. I used these in my 396 small block with AFR 180s. These are a couple of heat values cooler than the recommended starting plugs. The bases appear to be stainless rather than the black that is shown in the image.
