NGK Ruthenium HX High Ignitability Spark Plug for Select Buick, Cadillac, Chevrolet, and Ford 2004-2020

Fits select 2004-2020 Buick, Cadillac, Chevrolet, and Ford models.

NGK Ruthenium HX High Ignitability spark plugs represent the pinnacle of modern ignition technology, designed specifically for today's high-efficiency engines. Utilizing a patented ruthenium alloy, these plugs provide superior durability and oxidation resistance compared to traditional precious metal alternatives. The advanced DFE (Double Fine Electrode) and PSPE (Projected Square Platinum Electrode) tip designs ensure a more complete fuel burn, resulting in quicker throttle response, a smoother idle, and more reliable cold starts.

Each plug is engineered with a ultra-fine 0.4mm ruthenium center electrode and a 0.8mm platinum ground electrode to maximize spark energy while minimizing the required voltage. The pure alumina silicate ceramic insulator and copper core provide exceptional heat transfer and strength, while the trivalent metal plating protects against corrosion and seizing in the cylinder head.
