Zündverteiler 123 Volvo B18/B20

Brand new distributor with several different advanced curves. Your original ignition coil can be used with this new 123 distributor, as long as it is in good shape.
Coil has only one connector, this is for the black wire. The red wire has to be powered by 12 Volt when the ignition switch is on. The aluminum housing makes ground connections via the engine.
Keep in mind that this new item will give a stronger spark, which might cause worn cables and coils to fail.
