HKS 10 Hyundai Genesis Coupe 3.8L M-Series Spark Plugs (Heat Range 8) - Single - 50003-M40XL

• 0.6mm Iridium alloy center electrode
  Uses an iridium alloy center electrode that reduces the required voltage and improves ignitability while providing excellent durability.
• Ground electrode with platinum square tip
  improves wear resistance and improves ignitability when combined with iridium alloy center electrode. In addition, the tip can be shortened, and the tapered shape secures space volume.
• Short type seismic grounding
  electrode By shortening the length of the electrode and optimizing its cross-sectional shape, we have achieved a reduction in mass while increasing the section modulus. Contributes to improving the strength and durability of the ground electrode.
• ThermoEdge
  Carbon buildup caused by long-term idling and various combustion environments, including the air ratio, can reduce insulation and cause misfires. By providing a thermo-edge at the tip of the insulator, a micro discharge is generated to burn off the accumulated carbon, ensuring insulation at all times.
• The gap between the insulator at the tip of the auxiliary spark gap
  and the ground electrode surface is narrowed to generate discharge, and like ThermoEdge, it suppresses carbon buildup and prevents fogging and fogging.
