Ignitor II Electronic Ignition conversion, 8 cyl. The Ignitor II takes the Ignitor a step further by adding a powerful new microcontroller, that controls the dwell period, for the best possible spark over the entire RPM range. Ignitor II offers enhanced performance levels only found in more expensive box type ignition systems. Compared to point type systems Ignitor II develops on average 4 times more available energy between 3,000 and 5,000 RPM, and 2 times more available plug voltage. Higher RPM performance is improved when used with the Flame-Thrower II super low resistance 45,000 volt coil.
