• 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.

• Service Life & Performance - Field tested durability with a 30,000 mile service life.

• Corrosion Resistant - Zinc-Chromate coating for maximum protection to the elements which also acts as a release agent = no more seizing.

• Alumina Silicate Insulator - Virtually pure silicate to insure dielectric and physical strength, as well as better heat transfer away from the tip for maximum performance.

• Corrugated Ribs - Eliminates "flashover", which can cause misfiring and engine damage, especially in damp environments.
