Experience superior performance with our Iridium Spark Plug, designed specifically for your Harley-Davidson. This spark plug is six times harder than platinum, enabling it to withstand extreme temperatures up to 4,000°F. The iridium electrodes are ingeniously crafted to a minuscule 0.4mm, reducing voltage requirements while enhancing firing performance.
Additionally, the 360° laser welding of the electrode guarantees a seal that resists wear, even in the harshest conditions. The ground electrode features a tapered cut and U-groove design, creating a larger volume area for the flame's center, ensuring optimal combustion.
