Description


The Autolite Spark Plug is engineered for optimal performance, featuring a 14 mm thread, 0.375 in reach, gasket seat, and resistor. Its solid copper core center electrode ensures excellent thermal and electrical conductivity, while the high nickel alloy side electrode offers superior durability. The high alumina multi-rib insulator prevents flash-over, reducing misfires. Designed with a heat-fused glass composite resistor center seal, it provides effective EMI noise suppression and a leak-proof seal. Ideal for various applications, this spark plug delivers reliable ignition and longevity.
