Delphi Announces New Ignitions Coils for More Than 11 Million Vehicles

Delphi announced six new ignition pencil coils covering more than 11.4 million Chrysler, GM and Toyota vehicles from 1998 to 2011. Part numbers:  GN10309, GN10310, GN10311, GN10312, GN10313, GN10314.  

As of January 1, 2013, ignition coils carry a three year / 36K mile warranty. This applies to coils purchased after January 1, 2013. All other ignition related products still carry a 12 month /12K mile warranty. Coils purchased on or before December 31, 2012 carry a 12/12K mile warranty.

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 can also fail, causing energy to escape. 

Why Delphi for Ignition Coils

Delphi backs up its innovative ignition coil design with intelligent manufacturing and uses a winding process technique to control the length of wire between adjacent windings. More length results in greater voltage differences, which can create more pressure that could break down the insulation and wire coating.

Delphi has analyzed the environment that ignition coils must withstand and is combating failure issues with high-quality design and materials, including high quality wires and wire coating that resist 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 insulation quality and reduces the chances of energy punch-through failures.
