The NGK Spark Plugs CR9EH-9 spark plug is engineered for dependable ignition performance, efficient combustion, and long-lasting service in compatible powersports and small-engine applications. This spark plug uses a copper-core design to help transfer heat away from the firing end, supporting consistent operating temperatures and reliable performance under demanding conditions.
Its pure alumina silicate ceramic insulator provides high strength and efficient heat transfer, while the trivalent metal plating helps resist corrosion and seizing during installation and service. Triple seals are designed to help prevent leakage, and the corrugated insulator ribs help reduce the risk of flashover for dependable ignition. The CR9EH-9 is a heat-range 9 spark plug with a 0.035-inch gap, making it suitable for applications specified for this model and configuration.
