LIFESPAN / DURABILITY |Iridium alloy is 6X harder and 8X stronger than Platinum
Iridium with Rhodium Center Electrode -- DENSO uses the highest concentration of Iridium of any spark plug and outperforms in the most severe engine temperatures, resisting oxidation and voltage wear for over 100,000 miles.
Platinum Ground Electrode -- extends the life of the plug by resisting gap erosion.
Patented 360-Degree Laser Welding -- creates the highest quality bond for structural support of the center electrode.
PERFORMANCE / IGNITABILITY
0.7 mm Fine Wire Iridium Center Electrode -- improves ignitability for more horsepower, faster easier starts and fewer misfires under heavy loads.
DENSO Warranty Information:12 months on A/C Evaporator Cores, A/C Compressors, A/C Compressor Clutches, A/C Condensers, Radiators, Fuel Injectors, Fuel Pumps, Fuel Tank Sending Units, Ignition Coils (COP), Alternators, Starters, and Mass Air Flow Sensors. Parts subject to normal wear and tear are not covered (Filters, Ignition Wires, Oxygen Sensors, Spark Plugs, Wiper Blades, etc.).
