The NGK Spark Plugs CR9EK spark plug is engineered to provide dependable ignition performance for compatible powersports and small-engine applications. This plug features a copper core that promotes efficient heat removal, helping support consistent operation under demanding conditions. The CR9EK model is designed for reliable fitment in applications that specify NGK Spark Plugs part number 4548.
A trivalent metal-plated shell provides enhanced resistance to corrosion and helps reduce the risk of seizing during installation or removal. The pure alumina silicate ceramic insulator delivers high strength and efficient heat transfer, while the triple-seal construction helps prevent combustion-gas leakage. Corrugated insulator ribs further reduce the possibility of electrical flashover, supporting stable spark delivery and dependable engine performance.
When replacing a spark plug, verify that the vehicle or equipment manufacturer specifies the NGK Spark Plugs CR9EK model and manufacturer part number 4548. Proper fitment and correct installation are essential for maintaining ignition reliability, heat control, and service life. This product is supplied as an individual spark plug for compatible applications.
