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
0.4 mm Fine Wire Iridium Center Electrode -- achieves higher ignitability and requires lower spark voltage to enable high-response driving with fewer misfires. As a result, acceleration improves in comparison with normal plugs.
EFFICIENCY / FUEL ECONOMY
Twin Tips ① -- allow the spark plug to create the fastest and largest spark concentration and explosion, which translates into more power and superior fuel economy.
