FEATURES
• Senses current levels in the coil & adjusts the dwell to maintain peak energy throughout entire RPM range.
• Develops, on average, 4 times more available energy between 3000 and 5000 RPM’s and twice as much plug voltage as point-type systems.
• Ignition energy is sustained and coil life is increased when peak current level is reached just prior to spark. • More stable timing.
• Use with 18-5472 “Flame Thrower II” Coil for optimum performance
