NGK Ruthenium HX Spark Plugs (11-14 3.6L)

Start Your Engines With Ease. Upgrade your Dodge Challenger’s engine by installing NGK’s Ruthenium HX Spark Plugs. Unlike your vehicle’s stock plugs, these NGK items is built for engines that demand high ignitiability. They also come with pure alumina silicate ceramic insulators, which increases the plugs’ strength and provides better heat transfer. As a result, these ruthenium spark plugs will last longer, so you can start your Challenger without any problems.

Features NGK’s Double Fine Electrode Design. NGK’s Double Fine Electrode (DFE) design promotes the plugs’ spark energy, allowing them to ignite a wider range of air-fuel ratios. Thanks to this, you’ll get quicker and smoother vehicle starts with very little risk of failing.

Moderate Mechanical Expertise Is Required. You need to at least have a moderate mechanical skill level to ensure that each spark plug is properly secured to your vehicle. Fortunately, they boast a standard design, so it’ll only take you 2 hours to complete the task.

Includes NGK’s Warranty. These spark plugs are backed by NGK’s warranty. To learn more about the warranty’s terms and conditions, as well as its exclusions, please visit the manufacturer’s website.
