Autolite 405 Copper Resistor Spark Plug
The Autolite Spark Plug is selected for engines that must retain steady ignition performance during wide temperature shifts often experienced in utility vehicles, agricultural equipment, or older carbureted engines. The plug employs a one-piece terminal stud to preserve electrical continuity through every ignition event, even when engines shake or cycle rapidly at idle. Its copper-core center electrode manages thermal loading to help resist fouling in combustion chambers that run rich or operate at inconsistent temperature ranges. With a high-nickel side electrode resisting erosion over prolonged runtime, the Autolite 405 supports clean ignition in long-service environments.
