Help ensure fast starts, consistent engine performance and optimized fuel efficiency with Delphi Technologies ignition coils. Delphi has analyzed the tough environment that they must withstand and discovered how vibration, temperature changes and even the failure of other components, such as spark plugs, can cause them to fail. Specifically, these stresses can cause the wiring to break or have shorts. The insulation inside them could also fail and cause energy to escape. Delphi is combating these issues with innovative design and high-quality materials.

• Designed and endurance tested to resist the common stresses that cause failure.
• Efficient coil design that ensures the power in the coil has a streamlined path to the spark plug, reducing occurrence of shorts.
• Use of a special winding process controls 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.
• 6 weld positions (typically more than other brands), and an electrostatic paint coating, which results in consistent coil inductance and prevents lamination separation.
• High quality wires, as well as high quality wire coating that resists the cracks, pin holes and imperfections that most often lead to failure issues.
• Epoxy vacuum technique to reduce air bubbles in the epoxy, since having fewer air bubbles increases the epoxy's insulation quality and reduces the chances of energy punchthrough failures.
