Delphi employs winding process strategies to manage the distance of wire between neighboring coils; This is crucial because increased distance results in higher voltage variations, which can generate additional stress that may compromise the insulation and wire coating.
We back our ignition coil design with proven materials, such as high quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues
Delphi ignition coils are engineered to OE specifications; Built with the benefit of more than 100 years of Delphi's OE heritage, our coils are designed and endurance tested to resist the common stresses that cause failure
Epoxy vacuum techniques reduce air bubbles in the epoxy, because having fewer air bubbles increases the epoxy's insulation quality and reduces the chances of energy punch-through failures
