Like all Dyna coils these coils are high quality, American made performance coils, designed to provide spark voltages in excess of 30,000 Volts and spark energies second to none. These Dyna coils can be used in combination with all OEM and aftermarket electronic and points type ignition systems. Coils are available in 6 and 12 Volt with either dual or single tower for use with 2 or 4 plug heads, and Single or Dual Fire ignition systems. If peak performance is your goal, install Dyna coils today. You can't buy a more reliable, more powerful coil for Harley-Davidson motorcycles. Wiring diagram is included with each set of coils.
Note: 5 Ohm coils are for use with points ignition as well as for street use with a Dyna "S" ignition. 3 Ohm coils are for use with electronic ignition or race use with a Dyna "S" ignition. The ZPN232287 coils are fitted serial and consequently work as a 12 Volt 3 Ohm coil.
