Abstract
A spark plug coil assembly has a primary core bearing primary windings and a secondary winding spool around which secondary windings are wound and in which the primary core is received. A case receives the spool with core. The entire case can be made of composite Iron to function as a magnetic return path for the core, or a composite Iron shield can be overmolded to an otherwise plastic case.
