Extreme Performance From the Start. Experience extreme performance as soon as you turn on the ignition with these NGK Iridium IX Spark Plugs. Designed for the performance enthusiasts, these spark plugs have a highly ignitable iridium electrode tip that also helps prevent fouling. These spark plugs are also designed to boost throttle response and provide stable sparks each and every time. The ground electrode, meanwhile, sports a tapered design that lets the flame expand faster in a wider area.
Copper Core Aids in Better Heat Removal. The combustion chamber of high-performance cars can get a little too hot. Good thing that these spark plugs have a copper core, which helps remove more heat. In addition, the highly durable insulators are made from pure alumina silicate ceramic for its excellent heat transfer properties. They also sport corrugated ribs, which prevent flashover that eventually damages the ignition coil.
Engineered From the Best Materials. These spark plugs are made to last, engineered using the best quality of materials for durability and performance. Enhancing the components’ durability is the trivalent metal-plated finish. This creates an anti-corrosion layer and also prevents the spark plugs from seizing. Finally, the triple seals help prevent all kinds of leaks.
Straightforward Installation. Installing these spark plugs required only basic hand tools. After removing the old spark plugs, simply put these new ones in their place. You can accomplish this in approximately 1.50 to 2 hours.
Comes With a 1-Year Warranty. These spark plugs come with a 1-year NGK warranty that covers construction and material defects. Their estimated longevity is about 50,000 miles. Kindly contact the manufacturer if you need more information about the warranty policies.
Application. These NGK Iridium IX Spark Plugs can be installed on 2011-2014 models of the Dodge Challenger with 3.6L engines.
