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.

This product was easy to install and improved the running of my 72 dodge dart took about 30 minutes

Easy to install. The instructions are clear and easy to understand. Installed this in a rebuild and it fired right up and ran smooth as silk once I had the timing dialed in. It's PerTronix! They've never let me down.

Easy install. I've definitely noticed that my older Mopars start and run much better with Pertronix. This was my third conversion to Pertronix

Received the kit okay but have not yet installed it. I have an old tractor with a PerTronix unit in it and it works well.

I previously had great results with these in two old Fords, now tried in my Dodge - same results. Starts and runs better, no more fiddling with points every few months.

Was having trouble with ignition modules in my old 440 ci hot rod, installed this item with a new coil and got rid of ballast resistor and ignition module, all good now...
