Abstract
A spark plug coil assembly includes a primary core inside a secondary winding spool that is formed with a closed end. A terminal is embedded in the closed end of the spool and the secondary windings are terminated to the terminal, with the terminal being couplable to a spark plug. Ignition voltage generated in the secondary windings is thus routed to a center of the secondary windings to terminate at the terminal. No pole piece need be disposed between the primary core and the closed end of the spool.
