The NGK Iridium IX Spark Plug, a premium spark plug, delivers the ultimate in performance. Featuring a fine-wire iridium alloy center-electrode tip and a nickel alloy ground electrode for maximum engine horsepower and torque, the NGK Iridium IX Spark Plug is designed specifically for the performance enthusiast and provides extreme ignitability, improved throttle response, and advanced anti-fouling. The durable Iridium IX Spark plugs, which enable complete fuel ignition in the combustion chamber via the spark they create, are built to last between 40,000 and 50,000 miles. While spark plugs are built for durability, over time, your current spark plug can become fouled, worn, and less effective. With this in mind, if your vehicle exhibits bad spark plug symptoms including slow acceleration, poor fuel economy, or engine misfires, you may need a car spark plug replacement. Trust in NGK, the number 1 spark plug supplier, to provide Iridium IX Spark Plugs that showcase the best in performance and fitment. Please note, these spark plugs are pre-gapped for general use, however, you will need to adjust this gap to fit the needs of your specific application.
