NGK Laser Iridium Spark Plugs (11-21 3.6L)

Faster Starts, Longer Life. For no-nonsense spark plugs that starts your Challenger in a snap, these NGK Laser Iridium Spark Plugs are the way to go. They feature an iridium tip, which is 6 times harder than platinum, for greater ignitability, smoother acceleration, and a considerably longer lifespan. The platinum pad welded to the back of the ground electrode extends the lifespan of the iridium tip.

Copper Core for Better Heat Removal. To ensure that the heat from the combustion chamber is removed efficiently, NGK used copper for the electrode core of these spark plugs. Moreover, the insulators are engineered from pure alumina silicate ceramic for its excellent heat transferring and dissipating properties. To prevent flashover, which damages the ignition coil over time, the insulators feature corrugated ribs.

Made From Premium-Grade Materials. From the ceramic insulator down to the iridium tip, these spark plugs are constructed only from the best quality of materials. These spark plugs are also trivalent metal-plated for excellent corrosion resistance and anti-seizing capabilities. Finally, they are triple-sealed to ensure that there won’t be any leakages.

Easy and Hassle-Free Installation. All you need for installing these spark plugs are basic hand tools. You can directly fit them into the original locations in the engine compartment. Complete installation can be finished in about 1.50 to 2 hours.

Backed by a 1-Year Warranty. These spark plugs come with a 1-year warranty against defects on the workmanship and materials. They have an estimated longevity of 100,000 miles. If you have any questions regarding the warranty terms and conditions, please get in touch with the manufacturer.

Application. These NGK Laser Iridium Spark Plugs can be fitted to 2011-2021 Dodge Challengers with 3.6L engines.
