Our total loss coils are designed for use with inductive ignition systems like the Jetinetics Heat, One Shot, KV, and other inductive systems. They are powerful, reliable, and have easy mounting features to make installation a breeze. This 3.0 OHM coil is designed to produce a powerful, reliable spark and is intended for recreational use. They draw less current than their 1.5 Ohm counterparts and produce a much powerful but slightly less intense spark. These are intended for recreational use and can be run for prolonged riding periods without risk of damage to ignition components. Battery life will be significantly longer than with 1.5 OHM racing coils.
