Description of Delphi GN10426 Pencil Coil

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 in turn create more pressure that could break down the insulation and wire coating. Delphi's ignition coils are engineered to Original Equipment specifications. Delphi's ignition coils are designed 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. 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. Delphi's coils are designed and endurance tested to resist the common stresses that cause failure.

Works well but needs filing to fit

Appears to work . Fixed my misfire problem. BUT, as others have written, it doesn't fit. In the upper part of the shaft, near the harness, there are four small plastic protrusions. They are designed to slide into the hole for a snug fit. Unfortunately they stick out too far. My old one was 23mm across a pair of these cleats, and this one is 24mm. I filed those little bumps and they fitted. Didn't have time to go back and order something else. So it took me about 10 minutes to do a small upgrade

Pros
  • Delphi ignition coils are made from proven materials such as high quality wires and wire coatings that resist cracks, punctures and defects that most commonly cause breakdowns
Cons
  • Almost everything is fine
