Description:
The NGK CR10EK Multi-Ground Spark Plug is engineered to meet specific manufacturer ignition requirements while delivering reliable spark performance in demanding operating conditions. Its multi-ground electrode design improves ignition capability and is less sensitive to increased voltage requirements caused by gap growth, making it a strong choice for high-revving engines and performance-focused applications.
Like NGK’s standard plugs, the CR10EK is built with premium materials for durability and consistent operation. Corrugated ribs help prevent flashover, while the pure alumina silicate ceramic insulator provides superior strength and improved heat transfer. A copper core helps remove heat efficiently, and triple seals help prevent leakage for dependable long-term performance. This resistor-type spark plug is designed for applications requiring a 10mm thread, projected tip, and dual ground electrode configuration.
