Part #: EDL-Coil1.5OHM

EnDuraLast 1.5 Ohm Dual Tower ignition coil (sold individually - normally require two)

The optional mounting bracket is recommended. Additional modifications may be required to fit depending on your specific application.

NOTE: The terminals are not-polarized, so you can connect these either way. The positive side of the coil would be where you may require additional “keyed on” power. The negative side of the coil would be used for the ignition trigger or tach wire.

Application: 1.5 ohm dual tower coil, works with aftermarket electronic ignitions and will replace stock coil on some applications
Make/Model: BMW Airhead & Moto Guzzi
Model Years: BMW - 1981 and on with transistorized ignitions

These high tech, quality coils are designed for maximum performance. They produce spark voltages in excess of 30,000 volts and spark energies second to none. EnDuraLast Coils are made to replace stock coils. These Coils work with point ignitions, aftermarket electronic ignitions and factory electronic ignitions. Before selecting a coil, check the coil primary resistance requirements as specified by the manufacturer of the ignition being used. Our EnDuraLast electronic ignition for Airheads needs to see 3.0 ohms from the coils weather you are single or dual plugged (single plugged bikes should use the 3.0 ohm coil, dual plug modified heads will use 2 of the 1.5 ohm coils.) Each coil has two towers. One 3.0 ohm coil will replace the pair of original Bosch single tower coils.

If you have an Airhead with the transistorized ignition system (post 1981) you would want to use the EnDuraLast 0.7 ohm coil. Although some people choose to use 1.5 ohm coil, which also seems to work well.

For direct factory replacement you may care to select the OE coils for your given application.


  • High voltage and primary terminals machined from brass.
  • Ultrasonically welded and sealed against moisture.
  • Compact size fits easily under stock covers.
  • Peak gap current in excess of 50mA.
  • High impact thermoplastic housing.
  • Over 40,000 volts per output.
  • Accepts 7 to 8.8mm wires.

NOTE: The terminals are not-polarized, so you can connect these either way.
