Autolite 4123 Copper Resistor Spark Plug
The Autolite Spark Plug’s copper core electrode manages heat buildup and improves resilience in combustion chambers exposed to carbon deposits or fluctuating loads. The high-alumina multi-rib insulator delivers strong dielectric strength, helping prevent flashover that may interrupt engine rhythm. A heat-fused glass composite resistor seal ensures EMI suppression and a 100-percent gas-tight barrier. High-nickel alloy electrodes preserve firing edges despite repeated electrical and chemical exposure. The nickel-plated shell contributes additional corrosion resistance, especially valuable in motors exposed to moisture or infrequent shutdown cycles. The Autolite 4123 is well-adapted for applications requiring consistent firing throughout extended service intervals.
