Description

The Autolite AP103 is a platinum spark plug designed for superior performance and durability, especially in older engine applications. It features a platinum center electrode firing tip for quicker firing, smoother starts, and enhanced acceleration. The platinum tip resists gap erosion for a longer service life. Its high alumina ceramic insulator provides excellent thermal conductivity and insulation, while the multi-rib design prevents flash-over. The nickel-plated shell resists corrosion for added durability.
