Standard Motor Products DR-46 Ignition Coil

100% pure copper windings in primary and secondary bobbins improve durability and provide higher resistance to internal shorts and dielectric breakdown. Thermoplastic housing withstands heat stress for enhanced durability. External core made from oriented silicon steel ensures durability and longevity. Stainless steel spring resists corrosion. Tin-plated brass terminals improve electrical contact and protect against corrosion. High-dielectric epoxy injected into case and pulled into vacuum to eliminate air pockets and prevent moisture intrusion or thermal breakdown.
