The NGK Iridium spark plug delivers precise ignition control and improved combustion efficiency for smoother starts quicker throttle response and better fuel economy. Its ultra fine iridium center electrode is engineered for a consistently strong spark which reduces misfire potential and supports cleaner burning across a wide range of operating conditions. Attention to metallurgy and manufacturing tolerances ensures stable performance and long service life making it a dependable choice for daily driving and spirited use.

Designed for durability the plug features a corrosion resistant plated shell and a robust gasket seat for reliable sealing. A built in resistor helps suppress electromagnetic interference while precision manufacturing provides consistent thread engagement and heat dissipation. Routine inspection and correct gapping maintain optimal performance and the plug is suitable as a direct replacement where the specified thread size reach and heat range match vehicle requirements.
