The multi-rib high alumina ceramic insulator improves electrical insulation and heat dissipation, supporting stable performance in demanding engine conditions. A corrosion-resistant nickel-plated shell further protects the spark plug from rust and wear for long-term reliability.

Autolite copper spark plugs are designed to meet the performance needs of many gasoline engines and serve as a reliable replacement option for regular maintenance.
