The NGK Spark Plugs Iridium IX BR7EIX spark plug is engineered for reliable ignition, responsive performance, and extended service life in compatible engines. Its iridium center electrode is approximately 25% smaller than a platinum electrode and one-quarter the size of a conventional nickel electrode, helping focus the spark for efficient combustion and dependable starting.
Fitment: Designed for vehicles, powersports applications, and other engines that specify the NGK BR7EIX heat range and plug design. Verify application, engine specifications, and manufacturer recommendations before installation to ensure proper fitment. This spark plug is identified by NGK Spark Plugs manufacturer part number 6664 and vendor part number BR7EIX.
The ultra-small diameter center electrode reduces the voltage required to create a spark, which can support consistent ignition while helping reduce strain on ignition system components. A newly plated metal shell provides enhanced resistance to corrosion for improved durability in demanding operating environments. The NGK Iridium IX series is a practical upgrade for compatible applications where dependable ignition and long-term performance are priorities.
