Ultra-high ignitability technology delivers maximum power and a more complete fuel burn than traditional precious metal plugs. Utilizing a patented Projected Square Platinum Electrode (PSPE) design, these premium spark plugs concentrate spark energy to maintain optimal combustion across both rich and lean engine conditions. Drivers will notice immediate operational improvements, including quicker throttle response, a smoother idle, and more reliable cold-weather starts.
Advanced ruthenium alloy engineering provides unmatched durability and superior oxidation resistance under the highest combustion pressures and temperatures. The high-grade 0.4mm ruthenium fine-wire center electrode operates hand-in-hand with a 0.8mm platinum fine-wire ground electrode to prolong service life up to 60,000 to 120,000 miles. This specialized design prevents high-heat breakdown and peeling, making it the perfect upgrade for modern high-performance, turbocharged, or supercharged engines.
Premium construction safeguards defend your engine against misfires, electrical failures, and installation issues. Built with trivalent metal plating, the plug shell delivers exceptional anti-corrosion and anti-seizing protection without requiring anti-seize compound during installation. Integrated corrugated ribs along the pure alumina silicate ceramic insulator completely prevent electrical flashover while maximizing strength and thermal heat transfer.
