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
