Copper core electrode: Full copper center provides superior thermal conductivity and reliable performance in all conditions.
-
Copper-glass seal: Bonds the insulator, terminal post and center electrode for a 100% gas-tight, leak-proof seal and consistent voltage at the spark gap.
-
Multi-rib insulator: Reduces risk of flash-over for cleaner, more stable ignition.
-
One-piece terminal post: Adds mechanical strength and durability.
-
Built-in resistor: Minimizes radio frequency interference (RFI) and helps reduce electrode erosion.
