Ignition box performance without the box. The Ignitor III is our most advanced points replacement kit yet. It is lterally an ignition box inside your distributor. It features multiple sparks throughout the entire RPM range and a high resolution REV limiter accurate to +/- 50 RPM which is set by the user. The Ignitor III module generates 5 times more spark than points. This of course means more spark energy creating more horsepower and better mileage.

• Adjusts spark timing at higher RPMs to compensate for the inherent electronic delay
• Senses startup and develops more energy for quicker, easier starting
• Senses crank orientation from either the distributor cam lobe or a PerTronix magnet sleeve
• Thermal clad surface mount construction for high performance reliability
• Memory safe function for user settings
