The NGK Spark Plugs Iridium IX CR5HIX Spark Plug is designed to deliver reliable ignition, efficient combustion, and long-lasting performance for compatible powersports, motorcycle, scooter, and small-engine applications. This premium iridium spark plug uses a precision-engineered fine-wire center electrode to promote consistent spark formation while reducing the voltage required from the ignition system.
Fitment: Designed for vehicles and equipment requiring the NGK CR5HIX spark plug specification. Verify the application against the manufacturer's service information before installation to ensure correct heat range, reach, and engine compatibility. The NGK Spark Plugs Iridium IX model is a suitable replacement for compatible original-equipment spark plugs and is built for dependable performance in demanding operating conditions.
Construction: The iridium electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode. This ultra-small center electrode supports efficient ignition, helps improve throttle response, and can reduce the ignition voltage requirement, which may help extend ignition system component life. A newly enhanced metal shell plating provides improved resistance to corrosion for added durability in normal service environments.
Installation: Install the NGK Spark Plugs Iridium IX CR5HIX using the vehicle or equipment manufacturer's recommended torque, gap, and service procedures. Part number 7120 identifies this NGK Spark Plugs replacement spark plug and should be used when confirming compatibility with the applicable engine or ignition system.
