Abstract: A modular twin tower distributorless ignition coil assembly for an internal combustion engine includes a plurality of ignition coil subassemblies having a molded housing, a primary winding, a secondary winding, a laminated steel-plated armature, primary winding connectors and two high voltage towers for delivering the high voltage impulse induced by the secondary coil to respective engine spark plugs. Multiple ignition coil subassemblies can be coupled together through the use of integrally molded receptacle and plug connectors contained on the housing which ultimately co-operate with an engine control module to fire two, four, six or eight cylinder engines. Each modular ignition coil subassembly is substantially identical in its overall configuration and only minor modifications to the ignition coil subassembly are required to tailor an individual ignition coil assembly to fit into its position in a series of modules.
