Delphi has added four new ignition coils covering more than 1.7 million vehicles including Honda, Mercedes-Benz, Mazda and Lexus applications from 1999 to 2013.
Delphi backs up its innovative ignition coil design with intelligent manufacturing. Delphi uses winding process techniques to control the length of wire between adjacent windings. That’s important because more length results in greater voltage differences, which can create more pressure that could break down the insulation and wire coating.
Built with the benefit of more than 100 years of Delphi’s OE heritage, its ignition coils are engineered to OE specifications. Delphi coils are designed and endurance tested to resist the common stresses that cause failure.
Delphi has analyzed the environment that ignition coils must withstand and is combating failure issues with high-quality design and materials.
Delphi backs up its 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. It also uses a vacuum technique to reduce air bubbles in the epoxy. Having fewer air bubbles increases the epoxy’s insulating quality and reduces the chances of energy punch-through failures.
