Systems use magnetic rotors with Original Equipment spark advance mechanisms to retain the factory advance curves and replace points and condensers with a high-performance dual or single-fire system. Dyna S ignitions change timing less than 3° from 0-8000 RPM and feature improved performance, easy installation and a 3-year factory warranty. Completely self-contained, and install behind points cover.
