Meets or Exceeds Original Equipment Manufacture Specifications 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 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 This item is designed to be an exact replacement that meets or exceeds original specifications.
