The Dyna S High Performance Ignition System, designed for Harleys, is a
complete self-contained electronic ignition system built with the latest state-of-the-art engineering. This is the same ignition used by top racers over the
past 2 decades. The Dyna S is completely housed behind the ignition cover
and uses a magnetic rotor with the original spark advancer, so the factory
advance curve is maintained. Not legal for use in California on pollution
controlled vehicles - Check local laws before installing.
Note: Must be used with 5 ohm coils for street operation
