NGK Ruthenium HX High Ignitability Spark Plug Set of 4 (LKR7BHX) - Select 2007-2020 Chrysler, Dodge, Hyundai

Fits select 2007-2020 Chrysler, Dodge, Freightliner, Hyundai, and Jeep models.

NGK Ruthenium HX High Ignitability spark plugs represent a significant advancement in ignition technology for modern high-efficiency engines. Featuring a patented 0.4mm Ruthenium alloy fine-wire center electrode and a 0.8mm platinum fine-wire ground electrode, these plugs are engineered to provide maximum durability and oxidation resistance. The Ruthenium HX series is designed to replace specialized OEM DFE (Double Fine Electrode) and PSPE (Projected Square Platinum Electrode) designs, ensuring your ignition system operates at its peak potential.

By facilitating a more complete fuel burn, these spark plugs help restore throttle response, stabilize idle, and ensure reliable cold starts. The construction includes a pure alumina silicate ceramic insulator for superior dielectric strength and a copper core for efficient heat dissipation. To protect against the elements and simplify future maintenance, each plug is finished with trivalent metal plating for advanced anti-corrosion and anti-seizing performance.
