The NGK Spark Plugs Iridium IX Spark Plug DPR7EIX-9 is engineered to deliver reliable ignition, efficient combustion, and long-lasting performance for compatible powersports, automotive, and small-engine applications. Its iridium center electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode, helping produce a focused spark while reducing the voltage required from the ignition system.
The ultra-fine center electrode supports consistent starting, responsive throttle performance, and dependable operation across a wide range of engine conditions. NGK’s enhanced metal shell plating provides improved resistance to corrosion, helping protect the plug in demanding environments and supporting extended service life. The Iridium IX design is a practical upgrade for applications that require dependable spark delivery and stable engine performance.
Use this spark plug only where the NGK DPR7EIX-9 specification is listed for the engine or vehicle. It is sold under NGK Spark Plugs manufacturer and vendor part number 7803. Verify the application, heat range, reach, and plug design before installation to ensure proper fitment.
