NGK SPARK PLUG DR9EIX 4772

NGK Iridium IX Spark Plug - DR9EIX

The NGK Iridium IX spark plug represents the pinnacle of spark plug technology, engineered for superior performance and durability. Featuring an ultra-small diameter iridium center electrode, this plug requires less voltage to ignite, resulting in a more stable spark and extended ignition system life. The iridium alloy's exceptionally high melting point makes it ideal for demanding, high-performance engines. The plug's trivalent metal plating offers enhanced resistance to corrosion and seizing, while corrugated ribs are designed to prevent flashover. Its pure alumina silicate ceramic insulator provides robust strength and efficient heat transfer, complemented by a copper core for optimal heat dissipation. Triple seals ensure complete leakage prevention.
