Part #3377 · SKU denso-3377 · Backordered
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
• 0.7 mm Fine Wire Iridium Center Electrode -- improves ignitability for more horsepower, faster easier starts and fewer misfires under heavy loads.
