The Pertronix 1641 Ignitor is a points-to-electronic ignition conversion kit that installs inside the original distributor and replaces the breaker points and condenser with a maintenance-free magnetic trigger. The result is a stronger, more consistent spark, easier starting, and no points to wear or adjust. It runs on 12-volt, negative ground systems and fits the Nippondenso 4-cylinder distributors. Confirmed vehicle applications are listed below; match the year, model, and engine, and verify the vehicle still uses its original distributor before ordering.

FAQ
What does the Pertronix 1641 Ignitor kit do?
It converts a breaker-point ignition to electronic. The kit installs inside the original distributor and replaces the points and condenser with a magnetic trigger, so the ignition fires more consistently and needs no periodic point adjustment.
How do I confirm the 1641 fits my engine?
The 1641 is listed for the applications above. Match the year, model, and engine, and confirm the vehicle still runs its original distributor before ordering.
Does the 1641 require a specific voltage and ground?
Yes. It is built for 12-volt, negative ground systems. Installing it on the wrong voltage or ground polarity can damage the module, so confirm the vehicle's setup first.
Do the breaker points stay in the distributor?
No. The Ignitor replaces the points and condenser completely. Nothing from the breaker-point system stays in service after the conversion, and a matching ignition coil is recommended.
