  • Develops on average 4 times more available energy between 3000 and 5000 RPM, and 2 times more available plug voltage when used with Pertronix Flame-Thrower Coils
  • Adaptive dwell maintains peak energy throughout the entire RPM range, reducing misfires while improving engine performance
  • Synchronized peak current and spark timing reduces heat build-up and compensates for inherent electronic delay by adjusting the spark timing throughout the entire RPM range
  • Senses startup and develops more energy for quicker, easier starting
  • Pair with Pertronix Flame-Thrower Canister Coils 45001, 45011, 45111 for optimal performance


Ignitor Electronic Ignition Conversion Kits have proven themselves in applications ranging from race cars to tractors. It is the number one Electronic Ignition Conversion Kit to replace original mechanical points. A Pertronix Points Conversion kit allows you to run a stock distributor while improving the reliability and performance of your ignition system. The Pertronix Ignitor kits simply bolt to the distributor in place of the points assembly and provides a much more accurate trigger signal. This improves the timing accuracy and prevents ‘points bounce’ at higher rpm. The electronic technology also improves the dwell control to improve the spark output of the coil resulting in a hotter spark at the spark plug. With this dependable, self-contained, maintenance free electronic ignition system you'll never replace your points again.

When I first installed this in my car, it ran better than ever before. This is most likely because I had put off doing my points for a fue months. I did this job in the parking lot with the tools out of the back of my car. When I wired this up I made a big mistake. I was eager to get rid of the transistor box above my coil, and all the faulty wiring that went along with the point system. I kept the black 12 V power supply to the positive side of the coil, but removed another wire that went to the voltage regulator(as i found out later). I expected the voltage regulator to sense off the alternator or batterie. Anyways, my voltage regulator charged the batteries to 18V with the small amount of driving I did. This worked fine with the stock coil. But caused the 45000 voltage coil I installed the next day to run at 70,000 V, which was too much for the distributor to control. When you wire up your coil, you can get rid of the box with the ballast resistor, but the stock coil says that it is designed to run with this. The alternative to this system is too keep the points and wire up a capacitve discharge box to them. This runs a small signal current through the points and reduces wear(like a high teck version of the transistor box in the car now). I have heard people claim that the points don't need to be changed for five years. This sounds fun, and the capacitve discharge box reduces the time it takes to charge the coil. However this is offset by not having the adaptive dwell of this product. Obviously, the solution is to buy this product, the high voltage coil, and the capacitive discharge/ multi-spark box, then increase the gap on the spark plugs. However, I think this product with a high voltage coil is simple, and uses less engine bay space. This is most likely good enough for any stock car.
