NGK standard plugs are constructed for longer life and optimum performance.
    - Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
 - Corrugated ribs prevent flashover
 - Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer
 - Copper core aids in heat removal
 - Triple seals prevent leakage
