What is an MSD Ignition System?

Before we dive into the wiring diagram, let’s first understand what an MSD ignition system is. MSD stands for Multiple Spark Discharge, and it’s a high-performance ignition system designed to improve your engine’s performance. The MSD ignition system generates multiple sparks for each firing of the spark plug, resulting in a more complete combustion of the fuel mixture. This leads to better throttle response, improved fuel efficiency, and increased power.

An MSD ignition system typically consists of a distributor, ignition box, coil, and spark plug wires. The distributor sends high voltage from the ignition box to the coil, which then sends the voltage to the spark plug wires, and ultimately, the spark plugs.
