Single Plug Ignition Systems; pre-1981 using 3.0 ohms resistance coils, also works with aftermarket electronic ignitions.

Perfect for use with the EnDuraLast electronic ignition for Airheads, ELA44080, which needs to see 3.0 ohms from the coils whether 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.

PRODUCT OVERVIEW

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. 

If you have an Airhead with the transistorized electronic 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.
