Autolite 25 Copper Resistor Spark Plug
The Autolite Spark Plug is widely used in passenger vehicles requiring strong ignition performance under varying thermal conditions. Its one-piece terminal stud provides a reliable high voltage electrical connection, establishing a stable electrical pathway for high-voltage transfer. The copper core center electrode, which provides optimal thermal and electrical conductivity, aids in thermal control and improves resistance to fouling in engines running under mixed urban and highway conditions. The high alumina multi-rib insulator helps prevent flash-over, blocking unwanted energy travel that could lead to misfires in moisture-prone environments. The internal heat-fused glass composite resistor center seal provides high performance EMI noise suppression and a 100 percent leak-proof boundary, moderating electromagnetic interference for clear communication with sensitive onboard electronics.
