Delphi Product & Service Solutions has announced the addition of 23 new ignition coils to its engine management product portfolio, covering more than 7.3 million vehicles, including Audi, Chevrolet, Dodge, Hyundai, Ford, 
Honda and Jeep applications from 1991 to 2013. Part numbers include: GN10234, GN10396, GN10397, GN10398, GN10415, GN10416, GN10417, GN10418, GN10420, GN10422, GN10425, GN10426, GN10435, GN10443, GN10444, GN10446, GN10448, GN10451, GN10455, GN10457, GN10458, GN10507 and GN10509.
Why Ignition Coils Fail
Ignition coils operate in a tough environment. Stresses created by vibration, temperature changes and even the failure of spark plugs and other components can cause ignition coil wiring to break or short out. The insulation inside the ignition coil also can fail, causing energy to escape.
Delphi offers three reasons to choose its ignition coil line:
1. Precision Manufacturing Processes
Delphi backs up its ignition coil design with intelligent manufacturing. The company 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, the company says.
2. Tested and Proven with the Delphi Difference
Built with the benefit of more than 100 years of OE heritage, Delphi ignition coils are engineered to OE specifications. Delphi coils are designed and endurance-tested to resist the common stresses that cause failure.
3. Innovative Design and Materials
Delphi has analyzed the environment that ignition coils must withstand and is combating failure issues with high-quality design and materials. The company backs 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. Delphi also uses an epoxy vacuum technique to reduce air bubbles in the epoxy, because having fewer air bubbles increases the epoxy’s insulating quality and reduces the chances of energy punch-through failures.
