4702

Features & Benefits:
• 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.
