Ignition Coil

100% pure copper windings in primary and secondary bobbins improve durability and provide higher resistance to internal shorts and dielectric breakdown. Electronic ignition module profile and feedback signal ensures proper OE fit, form, and function. Thermoplastic housing withstands heat stress for enhanced durability. Internal core made from grain-oriented electrical steel limits loss factor within magnetic circuit to reduce heat that may reduce coil endurance. External core made from oriented silicon steel ensures durability and longevity.
