Key Features:

• Fine wire iridium alloy center electrode for a stable spark and durability
• Platinum-tipped ground electrode for ignitability and wear resistance
• Solid copper core for heat dissipation and conductivity
• Trivalent metal plating for corrosion and seizing resistance, which makes installation and removal easier
• Triple seals to help prevent combustion leakage
