IGNITION COILS
Purpose and Function.
Modern ignition systems are required to generate high ignition energy out-
puts in the most efficient way possible. Transformer type coils filled with
high temperature epoxy resin are available in different formats including
double output “waste spark” style units for 4 or 6 cylinder applications.
