Ignition Leads

In gasoline engines, Ignition leads are the components of the vehicle generating the spark needed for ignition and engine operation. The high voltage produced by the coil is transmitted to the spark plugs via the wires. The current passes from the spark plug to the combustion chamber to ignite the air-fuel mixture that operates the engine.

There are two types of cables, the one going from the distributor to the spark plugs and the cable going from the coil to the distributor.

If the plug wires are damaged it is important to change them as soon as possible in order to avoid:
  • Problems with sensors and vehicle control units.
  • Increased fuel consumption by leakage currents that prevent the correct spark, causing incomplete combustion.
  • Deformation of caps or cables on long journeys where the engine generates high temperatures.
  • Risk of fire by not having proper flame retardant treatment.
  • Low resistance to corrosion, chemicals and temperature.
