NGK Laser Iridium spark plugs feature a fine-wire platinum-tipped center electrode for stable spark and superior anti-fouling. The pure alumina silicate ceramic insulator provides superior strength and heat transfer, while the trivalent metal plating provides superior anti-corrosion and anti-seizing properties in marine environments.
- Fine-wire center electrode for improved fuel efficiency and lower emissions
- Copper core and ribbed suppressor seal prevent misfire and flashover
- Trivalent metal plating for superior corrosion resistance
- Meets Mercury Marine OEM specifications for engine protection
- Always check the gap prior to installation as per manufacturer specs
