Bosch Super 4 spark plugs
Your engine's new performance-enhancer: the high-power spark plug for retrofitting.
Another innovative idea from Bosch. The Bosch Super 4 operates on the state-of-the-art air-cushion-spark principle and is the first spark plug to feature four thin ground electrodes with one pointed, silver-plated center electrode.
This combination is unique in the world and has decisive benefits. The ignition spark always chooses the best path for reliable ignition according to the engine load.
Technical superiority - now available for your car.
The Bosch Super 4 does more than a conventional spark plug. In all situations, throughout its service life.
The advantages:
Noticeable improvement in acceleration
Significantly improved engine smoothness
Superior engine versatility
Electrode gap adjusted ex factory
