The NGK BP8HN-10 V-Power Spark Plug is engineered to deliver optimal ignition performance in Mariner and Mercury outboard motors. Its unique V-cut center electrode directs the spark to the edge of the electrode, enhancing spark development and increasing ignitability. This design reduces quenching and improves overall engine performance.
- V-Cut Center Electrode: Directs the spark to the electrode's edge, aiding rapid spark development and increasing ignitability.
- Nickel Center and Ground Electrodes: Provide durability and efficient heat dissipation.
- Standard Ground Configuration: Ensures compatibility with a wide range of outboard motors.
