Digital performance at analog prices! That's what you get from the HyFire VI-AL ignitions from Mallory. Mallory has taken their VI-A ignition box and added an easy-to-adjust digital rev limiter that adjusts between 4,500-12,000 rpm, and doesn't require chips. They use the newest microprocessor-controlled circuitry to deliver more power and quicker acceleration with less current draw. These highly efficient ignitions deliver multiple sparks per combustion event, so you get consistent, reliable performance throughout the rpm range. The durable, lightweight, extruded aluminum housing ensures maximum heat transfer. They are easy to install and work with points, OEM, or aftermarket electronic ignitions, or magnetic crank triggers.
