The NGK Spark Plugs CR5HSA spark plug is designed to provide dependable ignition performance for compatible engines and powersports applications. This standard replacement spark plug features a copper core that helps transfer heat away from the firing end, supporting consistent operation under changing engine conditions. Verify the application and engine model before installation to ensure proper fitment.
NGK Spark Plugs uses a pure alumina silicate ceramic insulator in the CR5HSA to provide high strength and efficient heat transfer. Trivalent metal plating helps resist corrosion and reduces the risk of seizing during service, while triple seals help prevent leakage. Corrugated ribs on the insulator help reduce the potential for flashover and support reliable spark delivery.
Designed as a replacement for applications specifying the NGK CR5HSA specification, this spark plug is identified by NGK manufacturer part number 7840 and vendor part number CR5HSA. Proper installation should follow the vehicle or equipment manufacturer’s specifications for spark plug gap, torque, and service interval. The compact plug design is commonly used in compatible small-engine and powersports applications, but fitment should be confirmed using the manufacturer’s application guide.
