      For Performance Enthusiasts. If you want more out of your Challenger from the moment you turn on the ignition, get these NGK Iridium IX Spark Plugs. Their electrode tip is iridium, which has a very high melting point, making these spark plugs very ignitable and excellent in minimizing fouling. In addition, the ground electrode features a tapered design so that the flame has more room to expand. You’ll also get consistent, stable sparking and experience enhanced throttle response with these spark plugs.

      Copper Core for Better Heat Removal. These iridium spark plugs have a copper core, which aids in the more efficient removal of heat from the combustion chamber. This is particularly important in cars intended for extreme performance. The insulators, on the other hand, are made from pure alumina silicate ceramic for incredible durability and heat transfer capabilities. Lastly, the corrugated insulator ribs aid in preventing flashover.

      Top Quality Construction. With their quality construction, you can count on these spark plugs to keep up with your high-performing Challenger for years. Apart from the premium-grade components, these spark plugs also have trivalent, metal-plated exteriors that help prevent corrosion and seizing. Moreover, these spark plugs have triple seals to stop all kinds of leakage.

      Simple and Hassle-Free Installation. To install these spark plugs, all you need are basic hand tools. Simply remove the old spark plugs from their chambers and replace them directly with these NGK ones. The entire process can take about 90 minutes to 2 hours.

      Covered by a 1-Year Warranty. These NGK iridium spark plugs are covered by a 1-year warranty against defects on the workmanship and materials. They are also estimated to last for about 50,000 miles. For any questions about the warranty policies, please get in touch with the manufacturer.

      Application. These NGK Iridium IX Spark Plugs are compatible with 2009-2022 Dodge Challenger with 5.7L HEMI engines.
