Abstract

An ignition coil set for a multicylinder internal combustion engine has a housing and a plurality of substantially identical ignition modules each having a primary coil and a secondary coil accommodated in the housing. A common connecting element is formed so as to provide positioning of the primary coils and the secondary coils and electrical contacting of terminals of the primary coils and low voltage side of the secondary coils when the coils are single spark coils or distribution of high voltage when the coils are formed as double spark coils, and also positioning of the housing which accommodates the ignition modules.
