High-Performance DENSO Double Iridium Spark Plug – Precision Engineered for Optimal Combustion
Premium double iridium construction ensures ultra-durability and consistent spark efficiency, reducing misfires and improving fuel economy. Laser-welded fine-wire center electrode (0.4mm) minimizes voltage requirements while enhancing ignitability for demanding engines. Direct OEM replacement (6G9N-18344-CA / BY481-LFR6A) compatible with CCH9006, 41LZAIME models, ideal for high-performance vehicles, turbocharged engines, and long-distance driving. Trivalent metal plating resists corrosion, extending plug life up to 60,000 miles. Exclusive anti-fouling design with tapered ground electrode cuts carbon buildup, maintaining peak power in stop-and-go traffic or extreme climates. Ultra-efficient combustion translates to lower emissions, meeting global environmental standards. Globally sourced at wholesale pricing – bulk orders available for workshops, retailers, or fleet maintenance. Authentic DENSO quality, rigorously tested for exact fitment and reliability.
