NGK Ruthenium HX Spark Plug Box of 4 (LTR7BHX)

With a 0.4mm Ruthenium alloy fine wire center electrode, these NGK Ruthenium HX spark plugs are built for modern engines that demand high ignitability. This advanced tip technology helps create a more complete fuel burn, which can lead to quicker throttle response, a smoother idle, and better performance when starting in cold weather. They are designed to fit a range of vehicles, including models like the Cadillac ATS, Ford F-150, and Lincoln MKZ.

The patented DFE and PSPE tip designs work together to concentrate spark energy, igniting a wider range of air-fuel mixtures, whether your engine is running rich or lean. This means you get improved performance across different conditions. The pure alumina silicate ceramic insulator offers superior strength and helps with heat transfer, while the trivalent metal plating resists corrosion and seizing, making installation easier and ensuring a solid connection. These plugs come in a box of four, ready to replace your old ones.
