Magnet Assembly

The Pertronix Ignition Magnet Assembly (Part Number 12813) is a precision magnetic component engineered for the Pertronix Ignitor II electronic ignition conversion system. This replacement magnet sleeve is essential for vehicles undergoing a modern ignition retrofit, providing the magnetic sensing function that enables the solid-state Ignitor II module to fire the engine's coil without traditional mechanical points.

The magnet assembly operates as the trigger mechanism within the Ignitor II ignition kit, detecting the rotation of the distributor shaft and signaling the electronic module to fire at precisely the right moment. This component eliminates point bounce, contact wear, and the timing drift that plagued conventional breaker-point systems. The compact design—measuring 4.85 x 1.7 x 6.15 inches and weighing just 0.08 lbs—integrates cleanly into standard distributor housings without modification, making it suitable for classic car restorations and vintage hot rod builds where OEM point-based ignitions are being upgraded.

This magnet sleeve is the correct replacement for Pertronix Ignitor II conversion kits on vehicles with standard distributor configurations. Pertronix ignition conversion systems have become the industry standard for points-to-electronic upgrades, trusted by engine builders and restoration shops for their reliability and ease of installation. The magnet assembly is a wear item that may require replacement if the ignition system is serviced or relocated, making it a practical spare to have on hand for any vehicle running the Ignitor II platform.
