The Autolite Spark Plug (Part Number: AUT65) is engineered to deliver quick starts, good fuel economy, and smooth acceleration. Featuring a solid copper core center electrode, it provides optimal thermal and electrical conductivity for better performance in all driving conditions. The high nickel alloy side electrode resists electrical and chemical wear, ensuring excellent durability. Designed with a high alumina multi-rib insulator to prevent flash-over and a heat-fused glass composite resistor center seal for high performance EMI noise suppression, this spark plug is built for reliability and longevity.
