The NGK Spark Plugs IFR6J11 Iridium Spark Plug is designed to provide dependable ignition performance, efficient combustion, and long-lasting service for compatible automotive applications. Manufactured by NGK Spark Plugs, this spark plug uses a fine iridium center electrode to support consistent spark delivery and reliable engine operation. The manufacturer part number and vendor part number are both 7658.
Featuring a pure alumina silicate ceramic insulator, the NGK IFR6J11 provides excellent mechanical strength and efficient heat transfer. Its copper core helps remove heat from the firing end, supporting stable performance across a wide range of operating conditions. Trivalent metal plating offers enhanced resistance to corrosion and seizing, helping simplify future removal and protect the plug during service.
Additional design features include corrugated ribs that help prevent flashover and triple seals that help prevent combustion-gas and moisture leakage. The IFR6J11 is intended as a direct-fit replacement for vehicles and engines specified for this NGK spark plug model. Always confirm vehicle application, engine configuration, and original equipment specifications before installation to ensure proper fitment and performance.
