PerTronix 1843 Details

The original Ignitor module is ideal for restorations. Ignitor Module Kits are extremely easy to install and fit into your original distributor to maintain your stock look. No additional ignition box is required keeping a clean look under the hood.

Ignitors are available for most distributors that came with mechanical breaker points and will cover AUTOMOTIVE, MARINE, INDUSTRIAL and AGRICULTURE applications.

For the specified Bosch four-cylinder ignition-conversion application.
Fits inside the specified original distributor to maintain a stock-looking engine bay.
Electronic ignition conversion replaces mechanical breaker-point operation.
Self-contained design requires no additional ignition box.
Designed for straightforward installation in the matching distributor.
Eliminates routine breaker-point replacement for a lower-maintenance ignition setup.
