NGK Ruthenium HX Spark Plugs (09-21 5.7L HEMI)

Heavy-Duty Spark Plugs You Can Count On. Start your Dodge Challenger’s engine without fail with NGK’s Ruthenium HX Spark Plugs. These spark plugs are crafted to help shorten your vehicle’s ignition time and improve its engine’s performance by generating a powerful spark at a faster rate. Additionally, they’re made from heavy-duty materials, which means they’re more durable and long-lasting than your Challenger’s stock components.

Boasts NGK’s Double Fine Electrode Design. Each of the plugs included in this kit features a Double Fine Electrode (DFE) design. DFE promotes spark energy, so the plugs can generate a wider range of air-fuel ration. The plugs are also built with a premium-quality copper core, which helps keep the plugs from overheating.

Medium Installation Level. Installing these spark plugs will only take you 2 hours. However, this task can be challenging for those who have little to no mechanical expertise. For this reason, it’s smart to have a buddy help you or hire a qualified mechanic to handle the installation instead.

Comes With NGK’s Warranty. This set of Ruthenium HX Spark Plugs is covered by NGK’s warranty. If any of the sparks is proven to be defective in workmanship or materials within a period of (60) days from the delivery date, the product will be repaired or replaced without cost. Please visit the manufacturer’s website for more information on the warranty’s terms and conditions.

Application. The NGK Ruthenium HX Spark Plugs fit all 2009-2021 5.7L HEMI Dodge Challenger models.
