The NGK Spark Plugs Iridium IX CR8EIX spark plug is engineered for dependable ignition, efficient combustion, and long service life in compatible powersports and small-engine applications. This premium iridium spark plug uses a fine-wire iridium center electrode to support reliable starting and consistent engine performance. The CR8EIX model is designed for applications requiring a high-performance replacement spark plug with durable construction and precise ignition characteristics.
Fitment: Confirm compatibility using your vehicle or engine manufacturer’s application specifications before installation. The NGK Spark Plugs CR8EIX Iridium IX spark plug is intended for select motorcycles, ATVs, personal watercraft, scooters, and other compatible powersports equipment. Always verify the model, engine, heat range, thread specifications, and required spark plug gap for your application.
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 helps reduce the voltage required for ignition, which can support easier starting and may help extend ignition system life. A newly developed metal shell plating provides enhanced resistance to corrosion for dependable service in demanding operating conditions.
