The NGK Spark Plugs Iridium IX CR8EHIX-9 spark plug is designed to deliver reliable ignition performance and long service life for compatible powersports and automotive applications. Its fine iridium center electrode requires less voltage to produce a strong spark, helping support consistent engine starting, smooth operation, and dependable performance.
Built as part of NGK’s Iridium IX product line, this spark plug features an ultra-small diameter center electrode that is approximately one-quarter the size of a conventional nickel electrode and smaller than a typical platinum electrode. The reduced electrode size helps improve ignition efficiency while reducing demand on the ignition system, which may contribute to extended ignition component life.
The CR8EHIX-9 also uses a specially plated metal shell with enhanced resistance to corrosion. This construction helps the plug withstand demanding operating conditions and maintain dependable performance over time. Verify the vehicle or equipment manufacturer’s application requirements before installation to confirm proper fitment, heat range, reach, and terminal configuration.
