Spark Plugs Autolite Spark Plugs use a copper center electrode sheathed in nickel chromium alloy to provide superior heat dissipation. A multi-rib insulator reduces the chances of “flash-over”, and a longer insulator, pioneered by Autolite, resists carbon fouling, allowing combustion deposits to burn away. We carry a complete selection of plugs for virtually any application. Please call for more details. Refer to spark plug reference chart on page 671.
