NGK Standard Spark Plugs (BR9HS) are engineered for reliability and efficient heat dissipation, featuring a copper core that promotes more efficient spark development. These plugs come pre-gapped for your convenience and utilize trivalent metal plating for superior anti-corrosion properties in marine environments. The pure alumina silicate ceramic insulator provides superior strength and better heat transfer.
- Pre-gapped to engine manufacturer’s specifications
- Copper core promotes heat dissipation and efficient operation
- Trivalent metal plating for superior corrosion resistance and anti-seizing
- Ribbed suppressor seal prevents spark "flash over" and misfires
- Replace all engine plugs at the same time for peak performance
