The NGK Spark Plugs Iridium IX CR8EIA-10 spark plug is designed to deliver dependable ignition performance, efficient combustion, and long service life for compatible powersports applications. As part of NGK’s Iridium IX line, it uses a fine iridium center electrode to promote a strong, consistent spark while requiring less ignition voltage than conventional spark plug designs.
Fitment: The CR8EIA-10 model is intended for vehicles and engines specified for this NGK application. Always verify the required plug model, heat range, reach, terminal style, and gap specification against the vehicle manufacturer’s service information before installation. This spark plug is supplied under NGK Spark Plugs manufacturer and vendor part number 4708.
Performance: The iridium electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode. Its ultra-small diameter helps reduce the voltage required for ignition, supporting reliable starting and potentially extending ignition system service life. The design also helps maintain dependable spark performance under demanding operating conditions.
Durability: A newly developed metal shell plating provides enhanced resistance to corrosion, helping protect the plug in challenging engine environments. With its compact CR8EIA-10 model design, NGK Spark Plugs Iridium IX technology provides a practical replacement option for compatible applications requiring consistent ignition and durable construction.
