An ignition coil for an internal combustion engine and a method of making the same in which layers of the secondary winding are separated by a non-filtering/non-segregating material embedded in an electrically insulated ignition coil housing. The preferred non-filtering secondary winding separator is a solid filament, non-absorbing/non-adsorbing mesh, such as a nylon mesh. Using the non-filtering/non-segregating secondary winding separator prevents filler damming when an ignition coil housing is manufactured using a vacuum encapsulation and curing process in which an encapsulation compound (e.g. a thermal setting epoxy) has solid additives (e.g. sand fillers). Non-absorbing/non-adsorbing separators are also advantageous because the separators do not alter the chemistry of the encapsulation compound.
