1.Tapered ground electrode
Improves combustion
2-Large copper core enables an improved heat transfer
3-Special ceramic material with high dielectric and mechanical strenght
4-Specific insulator design to prevent flashovers
5-Nickel-plated shell with rolled thrads provides complete anti-seize and corrosion protection
6-Fine center electrode design improves ignitability and provides longer service life
7-Laser welded precious metal pin on the center electrode provides higher wear resistance
8-Different electrode materials for different fuel applications (e.g. Ethanol)
9-Orientated ground electrode enables the right spark position and better ignitability
