Think of it as an Ignitor with brains.

Gain horsepower, quicker starting and longer plug life with the Pertronix Ignitor II; and you'll never change or adjust points again. The Pertronix Ignitor II shares the same features that make the current Ignitor so popular but has added 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, develops on average 4 times more available energy between 3000 and 5000 RPM and 2 times more available plug voltage. 50-State Legal EO#D57-2
