What is the air gap for the the distributor pick up module?

The air gap for a distributor pickup module typically refers to the distance between the pickup coil and the reluctor (or rotor) that it senses. This air gap is crucial for optimal signal generation; if it's too large, the signal may be weak or nonexistent, while if it's too small, it can cause interference or damage. Generally, the recommended air gap is around 0.008 to 0.020 inches, but it's essential to consult the specific manufacturer's specifications for precise measurements. Proper adjustment ensures efficient ignition timing and engine performance.
