This is an authentic factory OEM 12-volt dual-lead ignition coil made by Nippondenso for vintage Honda motorcycles. Designed for late-1970s parallel-twin models, this coil converts low-voltage battery power into high-voltage spark for both spark plugs through a wasted-spark ignition system The assembly features a light-beige insulated body with internal windings, dual-core metal mounting plate, two high-tension spark plug wires, and original terminal lead connections. It is an important part for restoring factory spark delivery and engine timing on Honda small-displacement twins.
