As engine technology evolves, coil-on-plug technology will continue to play an increasingly important part of ignition systems. One such technology is the pencil coil. NAPA® Echlin® are leading the way with quality parts and exceptional coverage for this growing category. Take our IC242 Ignition Coil for example:
Tech Tip: If there’s been a failure such as a short, we recommend replacing the spark plug while you’re replacing the pencil coil.
Silicone rubber boot withstands extreme heat and provides superior insulation
Stainless steel spring resists corrosion
Primary and secondary bobbins made from fiberglass-reinforced polyethylene terephthalate prevent voltage flashover for extended service life
Internal core made from grainoriented electrical steel limits loss factor within magnetic circuit to reduce heat that may affect coil endurance
External core made from oriented silicon steel for durability
Neodymium magnet produces max high voltage output at all speeds
Electronic ignition module profile and feedback signal matches fit, form, and function of original
Tin-plated brass terminals improve electrical contact and protect against corrosion
