Nickel-plated Shell No anti-seize required: nickel-plated housing eliminates the need to use anti-seize to prevent corrosion.
Laser weld 360˚ continuous laser weld fuses corrosion-resistant precious metal firing pin to base, which promotes durability and longest life.
Tapered Ground Electrode The tapered shape reduces flame shrouding for improved combustion and more power. Laser welded iridium-platinum alloy inlay promotes durability and longest life, and the copper core (when required) provides broader heat range to resist pre-ignition.
Copper Core Electrode The ultra fine wire design delivers exceptional ignitability and performance, while the copper core provides broader heat range to resist pre-ignition and fouling.
