Description
NGK CR7HSA-9 standard resistor spark plugs deliver reliable ignition performance for many motorcycles, scooters and small engines.
- Standard nickel-alloy plug with a copper core for strong spark, broad heat range and efficient heat dissipation
- High-strength alumina-silicate ceramic insulator for durability and stable dielectric performance under high temperatures
- Corrosion-resistant metal plating helps prevent seizing in the cylinder head for easier removal
- Triple-sealed design and corrugated insulator ribs help prevent combustion gas leakage and flashover
- 10 mm thread size with 0.5 in (12.7 mm) reach and 5/8 in (16 mm) hex, NGK heat range 7
- Resistor construction (about 5k Ohms) reduces electrical noise that can interfere with electronic systems
- Pre-gapped to approximately 0.031 in (0.8 mm); always verify and adjust gap to your service manual before installation
