The NGK Spark Plugs Iridium IX DR9EIX spark plug is engineered for reliable ignition, consistent performance, and extended service life in compatible powersports and small-engine applications. Its fine iridium center electrode supports efficient combustion while requiring less voltage from the ignition system than conventional nickel designs.
Fitment: Designed for applications that specify the NGK DR9EIX spark plug. Verify the vehicle or engine manufacturer’s application guide before installation to confirm proper fitment, heat range, reach, and gap requirements.
Performance: 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 reduces the voltage requirement, promotes dependable spark formation, and may help extend ignition system life. The enhanced metal shell plating provides improved resistance to corrosion for added durability in demanding operating environments.
Product identification: This spark plug is manufactured by NGK Spark Plugs and is identified by manufacturer part number 4772 and vendor part number DR9EIX. Install and torque the plug according to the engine manufacturer’s service instructions.
