The NGK Spark Plugs ZFR5F spark plug is designed to provide dependable ignition performance and long-lasting service in compatible gasoline engines. Manufactured by NGK Spark Plugs and identified by manufacturer and vendor part number 7558, this spark plug is engineered for applications requiring the ZFR5F model. Its copper-core construction supports efficient heat removal, helping maintain consistent operating performance across a range of driving conditions.
Trivalent metal plating provides strong resistance to corrosion and helps reduce the risk of seizing during installation or removal. The pure alumina silicate ceramic insulator delivers high strength and improved heat transfer, while the triple-seal design helps prevent combustion-gas leakage. Corrugated insulator ribs help reduce the potential for flashover, supporting reliable ignition and stable engine operation.
