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.
			
			Corrosion Resistant
			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.
			
			Corrugated Ribs
			Eliminate "flashover", which can cause misfiring and engine damage, especially in damp environments.
