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.
CAPA Certified or NSF Certified parts bear the seal of independent, third party organizations guaranteeing fitment and quality equal to original equipment. These parts may be required if your insurance company is paying for the repair.
