Pro-Cap Cap-A-Dapt Kit - Black (5" Dia Cap & Rotor Kit Fits Pro Mag 44 Pro Mag 12)
Product Information
MSD Pro-Mags are engineered for a wide variety of racing applications. Each Mag is supplied with a durable cap and rotor that has been tested for performance. When space permits, upgrading to a larger diameter magneto cap can further prevent chances of crossfire. Also, if you're using a timing control to retard the timing, a Cap-A-Dapt is highly recommended because the retard affects the rotor phasing.
