    Abstract: The unit includes a support housing (1, 10) containing two ignition coils (20) each for connection to at least one, and preferably two, associated spark plugs (SP). Each ignition coil (20) comprises a primary winding (21) and a secondary winding (24) disposed around the end arms (41) of a magnetic core or circuit formed by only two packs of plates (40) juxtaposed so that together they form essentially a figure-of-8 shape. The packs of plates (40) are identical, essentially E-shaped and are placed close together, face-to-face, so that together they form a squared figure-of-8 shape. Each of the packs of plates (40) has a notch (43) which extends from the back of the E into its central arm (42) and almost up to the edge of the free end thereof. Conveniently, inserts (50) of non-magnetic material are disposed in the notches (43) in the packs of plates (40).
