 Plug of Choice in Millions of Motorcycles, ATVs, and Scooters Triple-Gasket Sealing Process Virtually eliminates the possibility of combustion gas leakage through the shell. Most other manufacturers only use two seals. Solid-Copper Core Produces a more powerful spark with less firing voltage. Other manufacturers use a "copper coated" center core. Cold-Rolled Threads For easier removal and installation. Corrosion Resistant Zinc Chromate Coating double dipped for maximum protection. An NGK exclusive. Alumina Silicate Insulator Is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance. Corrugated Ribs Eliminate "flashover", which can cause misfiring and engine damage, especially in damp environments.
