Bosch Super's main features are a compound center electrode composed of a copper core surrounded by a nickel-chromium jacket, and an electrode gap which has been set at the factory. The center electrode's copper core serves to efficiently conduct the heat away to prevent the electrode from overheating. The nickel-chromium alloy protects the copper core against corrosion and ensures a high level of resistance to wear caused by spark erosion.

Bosch Super has a larger ground electrode than most other plugs, which provides better heat dissipation for unsurpassed reliability and maximum performance.
