electrode tip, providing excellent durability and a powerful, consistent
spark. A platinum disc welded to the rear of the ground electrode helps
extend service life, while the fine 0.6mm iridium tip delivers precise
ignition performance.
The longer insulator nose helps prevent
fouling, while corrugated insulator ribs help reduce the risk of
flashover. A triple gasket seal helps prevent combustion gas leakage,
providing reliable performance across a wide range of operating
conditions.
