A special thread and shell coating ensures quick and easy removal from aluminum heads and resists corrosion.
- A gold palladium insert extends life and improves resistance to corrosion
- The tapered tip provides better spark exposure to air/fuel mixture and allows the mixture to flow more easily through gap area for maximum combustibility
- Fouling resistance is improved with smaller diameter center electrode wire and insulator tip
- Plus, a copper-cored ground electrode runs cooler for extended life
