The Pertronix 91481 Ignitor II is a points-to-electronic ignition conversion kit for V8 engines using the IHC 359xxx to D4xxxxxx series 8-cylinder distributor, including the International Scout II. As an Ignitor II, it adds adaptive dwell control that adjusts spark timing to engine speed for a stronger spark at higher rpm. It replaces the points and condenser with a self-contained module and runs on a 12-volt negative-ground system.

FAQ
What does the Pertronix 91481 Ignitor kit do?
It converts the original breaker-point ignition to electronic. The Ignitor II replaces the points and condenser inside the existing distributor with a self-contained magnetic-trigger module, so the engine starts more reliably, holds timing better, and needs no points to clean, gap or replace.
What does the Pertronix 91481 fit?
It is designed for IHC 359xxx-D4xxxxxx series 8-cylinder distributor. Fitment is determined by the distributor, so check your distributor against the Pertronix fitment list before ordering.
What electrical system does the 91481 require?
It is built for a 12 volt negative ground system. Confirm your vehicle matches this voltage and ground polarity, because Ignitor kits are voltage and ground specific.
How is the Ignitor II different from the standard Ignitor?
The Ignitor II adds adaptive dwell control, which adjusts the coil charge time to engine speed. That supports a stronger spark at higher rpm and works with a wider range of ignition coils, while installing the same way inside the distributor.
