Ignition Leads

What are ignition leads?

Ignition leads are used to distribute the high voltage from the ignition coils to the spark plugs in a vehicle’s ignition process.


Why choose Valeo ignition leads?

Having more than 670 individual part numbers, Valeo ignition leads cover three O.E. high tension wire technologies: reactive, copper and resistive, to conduct the ignition spark into the spark plug of any modern vehicle, by respecting the vehicle technology.

For selected applications require a more affordable solution, Valeo also provides an alternative "value for money" lead set in resistive cable technology.

  • Reactive Technology: consists of a cable with carbon-coated fiber glass, wrapped with a wire
  • Copper Technology: the oldest technology, consists of a cable with copper wire core and a diameter of 7 mm
  • Resistive Technology: uses a fiberglass core impregnated with carbon. The diameter of these beams is 7mm or 8mm
