The NGK Spark Plugs Iridium IX CR7HIX spark plug is designed to deliver dependable ignition, efficient combustion, and long-lasting performance for compatible powersports and small-engine applications. Its iridium construction supports a strong, consistent spark while helping reduce the voltage required from the ignition system. This plug is a direct-fit replacement for applications specified for the CR7HIX model and should be matched to the vehicle or equipment manufacturer's fitment requirements before installation.
Feature: Ultra-fine iridium center electrode helps produce a focused spark and supports reliable starting, smooth operation, and responsive throttle performance. The electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode, helping improve ignition efficiency while reducing the required firing voltage.
Feature: Enhanced metal shell plating provides improved resistance to corrosion, helping protect the spark plug in demanding operating environments. The durable design also supports extended ignition-system life and consistent performance over the service interval recommended for the application.
Manufactured by NGK Spark Plugs, this Iridium IX spark plug carries manufacturer part number 7544 and vendor part number 7544. The CR7HIX model is intended for engines that call for this specific plug specification. Confirm the required heat range, thread configuration, reach, and application fitment in the vehicle or equipment service information before replacing the original spark plug.
