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. The Bosch Super 4 does more than a conventional spark plug. In all situations, throughout its service life.

Features & Benefits

  • Noticeable improvement in acceleration
  • Significantly improved engine smoothness
  • Superior engine versatility
  • Electrode gap adjusted ex factory

Additional Information

Please check with your vehicle manufacturer or workshop manual to confirm the suitability of this part for your vehicle.
