Triple-Gasket Sealing Process
Virtually eliminates the possibility of combustion gas leakage through the shell. Most other manufacturers only use two seals.
Produces a more powerful spark with less firing voltage. Other manufacturers use a "copper coated" center core.
Zinc Chromate Coating double dipped for maximum protection. An NGK exclusive.
Alumina Silicate Insulator
Virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance.
Eliminate "flashover", which can cause misfiring and engine damage, especially in damp environments.
