Pertronix 19413 Magnet Sleeve (only) for 1941 Ignitor Kit, Black

PerTronix Ignitor solid-state ignition systems deliver more energy with greater timing accuracy. The secret lies in the trigger magnets, which spin with the rotor and operate a switching module that requires no external control box. These systems are immune to heat, oil, and debris-and install in about 15 minutes with only two wires to connect. They come with a switching module, hardware, and instructions. Ignitor is an ideal choice for collector car restoration because they fit entirely under the distributor cap.
