For both stop-and-go urban traffic and long-distance motorway driving: Bosch Super always lives up to its name. That is why the Bosch spark plug with the copper core soon became the most widely sold in Europe.
The winning features:
Rapid attainment of operating temperature
High cold starting reliability
Protection of engine and catalytic converter
Set electrode gap
Super also stands for:
Top Bosch quality for virtually all vehicles and compliance with specific vehicle manufacturers' requirements. Plus a long service life guaranteed by excellent workmanship and high-grade materials:
The copper core of the center electrode is a good dissipator of heat and thus guards against thermal overload.
The nickel-chromium alloy of the center electrode provides corrosion protection for the copper core and ensures a high level of resistance to spark erosion.
