Delphi GN10452 Spark Plug Top Coil - High Performance Ignition Coil for Cars, Trucks & SUVs | Perfect for Engine Tune-Ups & Performance Upgrades

Delphi ignition coils are designed to operate as part of an integral engine management system to insert power into spark plugs and ensure fast starts, consistent engine performance and optimized fuel efficiency.

Delphi uses winding process techniques to control the length of wire between adjacent windings, that is important because more length results in greater voltage differences, and can 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
