The Iridium Long-Life Spark Plug is engineered to meet the highest OE standards for performance, durability, and emissions, making it a reliable choice for demanding driving conditions. Featuring DENSO's patented Iridium Alloy and fine wire center electrode, this spark plug delivers sustained spark performance for over 100,000 miles, lasting up to three times longer than conventional plugs. Its Platinum Needle Tip Ground Electrode promotes higher spark energy while reducing heat quenching, ensuring efficient ignition even under extreme temperatures exceeding 4,000 degrees Fahrenheit. The 360-degree laser welding process guarantees a robust bond and structural strength, while the Iridium alloy is six times harder and eight times stronger than Platinum, offering superior durability. Designed for fuel efficiency, this spark plug helps conserve fuel, making it an economical and long-lasting solution for high-performance ignition systems. With a flat seat type and advanced technology, it is built to endure the toughest conditions while optimizing engine performance.
