- 0.4mm Iridium tipped laser welded fine wire center electrode reduces required voltage and improves firing performance.
- Tapered cut U-Groove ground electrode increases ignitability and decreases quenching
- Machine rolled threads prevent seizing or cross threading during installation and removal
- 100% pre-fired to assure the highest quality possible
- Purified alumina powder insulator provides exceptional strength and thermal conductivity
- Five rib insulator prevents flashover
- Copper-glass seal bonds center electrode and insulator for a gas-tight seal
