Ducati Diavel Owners Manual: Cleaning and replacing the spark plugs

Ducati Diavel Owners Manual / Main maintenance operations / Cleaning and replacing the spark plugs

Spark plugs are essential to smooth engine running and should be checked at regular intervals.

The condition of the spark plugs provides a good indication of how well the engine is running.

Have the spark plugs inspected or replaced at a ducati dealer or authorised service centre; they will check the colour of the ceramic insulator of the central electrode (1): an even brown colour is a sign that the engine is in good running order.
