Experience unparalleled performance with our Iridium Spark Plug, designed specifically for your Harley-Davidson. This plug is six times harder than platinum, allowing it to withstand extreme temperatures of up to 4,000°F. The advanced design features iridium electrodes that can be shrunk to just 0.4mm, resulting in lower voltage requirements and improved firing performance.
The 360° laser welding of the electrode creates a durable seal that resists wear, even in the harshest conditions. Additionally, the ground electrode is engineered with a tapered cut and U-groove, enhancing the volume area for the flame's center, ensuring efficient combustion.
