The NGK Spark Plugs BR9EIX Iridium IX Spark Plug is designed for dependable ignition performance, efficient combustion, and long-lasting service. This Iridium IX model uses a fine iridium center electrode that is significantly smaller than platinum and conventional nickel electrodes. The ultra-small electrode design helps reduce the voltage required for spark formation, supporting easier ignition and helping reduce stress on ignition system components.
Built by NGK Spark Plugs, the BR9EIX combines advanced electrode technology with a durable metal shell featuring enhanced anti-corrosion properties. This construction helps the spark plug maintain reliable performance in demanding operating environments while supporting consistent spark delivery and extended service life. Its iridium electrode also promotes stable ignition performance across a broad range of engine operating conditions.
The NGK Spark Plugs BR9EIX Iridium IX Spark Plug is intended for applications specified for this plug model and heat range. Confirm vehicle, engine, and ignition-system fitment before installation, and replace the spark plug according to the equipment manufacturer’s recommended service interval. This product is identified by NGK Spark Plugs manufacturer part number 3981 and vendor part number BR9EIX.
