NGK 11-20 Chrysler 300 Ruthenium HX Spark Plug

If you're looking to give your modern vehicle's ignition system a solid upgrade, consider these NGK Ruthenium HX spark plugs. They're built with advanced OE technology and feature a patented Ruthenium alloy fine wire center electrode, measuring 0.4mm, paired with a 0.8mm platinum fine wire ground electrode. This setup is designed to concentrate spark energy, leading to a more complete fuel burn. You might notice a quicker throttle response, a smoother idle, and better performance when starting in cold weather.

NGK developed these plugs specifically for newer engines that require high ignitability. The Double Fine Electrode (DFE) design helps ignite a wider range of air-fuel mixtures, which is beneficial whether your engine is running rich or lean. The ceramic insulator is made from pure alumina silicate, offering superior strength and effective heat transfer, while the trivalent metal plating helps prevent corrosion and seizing. Plus, the corrugated ribs on the insulator are there to stop flashover, and the copper core helps dissipate heat.

These plugs fit a wide range of vehicles, including many Acura, Honda, Jeep, and Dodge models, in addition to Chrysler. They are a great choice if your vehicle originally used OE DFE type spark plugs or if you're simply looking for an aftermarket option that incorporates the latest in OE technology for improved performance and extended life expectancy.
