Description

The Autolite 6003 is a copper resistor spark plug designed for quick starts and enhanced durability. It features a copper core center electrode for thermal control and fouling resistance. The high nickel alloy electrodes provide extended life, and the long projection design improves ignition efficiency. Its multi-rib ceramic insulator offers superior insulation and strength, while the nickel-plated shell resists corrosion.
