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 ; Winding directly onto proprietary steel core for maximum efficiency
Delphi’s ignition coils are designed with proven materials, such as quality wires and wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues
