1.5 ohm dual tower coil, works with aftermarket electronic ignitions and will replace stock coil on some applications
Resistance: 1.5Ω primary resistance and 13.5kΩ secondary resistance
Inductance: 4.95mH primary and >20H secondary

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. The EnDuraLast electronic ignition for Airheads, ELA44080, 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.

If you have an Airhead with the electronic 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.
