Ballast Resistor 0.8 Ohm

The Ballast Resistor 0.8 Ohm from MSD Ignition is an essential component for classic and modified vehicles utilizing traditional points-style or early electronic ignition systems. This resistor is particularly beneficial for those restoring muscle cars, hot rods, or vintage trucks while upgrading their electrical ignition infrastructure.

Designed to protect ignition coils and spark plug wires from voltage spikes, the 0.8 ohm resistance value helps regulate voltage to an optimal level for ignition coils. This controlled voltage drop can extend coil life and reduce heat buildup in the ignition module, preventing arcing across contact points or electronic switches. The ballast resistor features precision wirewound construction for reliability.

Ideal for enthusiasts retrofitting vintage ignition systems or upgrading to higher-output coils, the installation of this ballast resistor is straightforward. It mounts inline between the battery and the ignition coil, making it a practical choice for various applications without interfering with other components.
