Masterparts offers a full range of ignition leads, suitable for most vehicle makes and models.

What does an ignition lead do in a car?

Ignition leads are part of a vehicle’s ignition system. They transfer high voltage power from the ignition coils to the spark plugs.

The powerful bursts of electricity create the spark that ignites the air-fuel mixture in the combustion chamber.

Only vehicles fitted with distributor and block, or pack, ignition coils use ignition leads to supply the high voltage output to the spark plugs.

In the more common “coil-on-plug” configuration, ignition coils are mounted directly on the spark plugs, rendering ignition leads redundant.

Types of ignition leads

There are three types of ignition leads:

  • solid copper core
  • carbon resistor
  • spiral-wound.

The conductive resistance and suppression of the materials determines which ignition system each type of lead is designed for.

When paired incorrectly, the voltage to the plugs can increase or decrease. This, in turn, can result in damage to electronic components or a faulty ignition process.

Take a look at the YouTube video Ignition Wire – An Introduction by Moss Motors for an overview of ignition leads and their function.

Signs of a malfunctioning ignition lead

Over time, and due to their proximity to the engine, ignition cables wear and crack. Apart from the visible signs of damage, common symptoms of a worn or failing ignition lead include a reduction in power, acceleration and fuel efficiency.

As the ignition process deteriorates, the engine misfires and eventually stalls.
