Description:
The Autolite 4265 Copper Spark Plug is engineered to deliver dependable ignition performance, quick starts, and consistent engine power. Its copper core center electrode provides excellent heat transfer, helping maintain proper operating temperatures while reducing the risk of fouling.
High nickel alloy center and ground electrodes provide improved durability and extended service life while ensuring stable spark delivery. The high alumina multi-rib ceramic insulator improves electrical insulation and heat dissipation, helping maintain reliable performance under demanding engine conditions. A corrosion-resistant nickel-plated shell further protects the spark plug from rust and wear for long-term durability.
Autolite copper spark plugs are designed to meet performance expectations for many gasoline engines and serve as reliable replacements for routine maintenance.
