The NGK Spark Plugs Iridium IX BR9HIX Spark Plug is designed to deliver dependable ignition performance, improved throttle response, and long-lasting service for compatible engines. Its fine iridium center electrode supports efficient spark formation while requiring less voltage than conventional nickel electrodes. This design can help reduce ignition system strain and promote consistent engine operation.
Built for drivers and equipment owners who demand reliable spark plug performance, the BR9HIX features an iridium electrode approximately 25% smaller than a platinum electrode and significantly smaller than a conventional nickel electrode. The reduced electrode diameter helps focus the spark for reliable ignition across a range of operating conditions. The updated metal shell plating also provides enhanced resistance to corrosion, supporting durability in demanding engine environments.
Manufactured by NGK Spark Plugs and sold under the NGK Spark Plugs brand, this Iridium IX spark plug carries manufacturer part number 5687 and vendor part number BR9HIX. It is intended as a direct replacement for applications specified for this plug model.
