Ignition Cable: Description and Operation
PURPOSEIgnition wires conduct high secondary voltage from coils to each spark plug in proper sequence (firing order).
CONSTRUCTION
Wires are constructed with a carbon impregnated, multi-filament synthetic fiber core. To endure under hood temperatures, the core is surrounded by heat resistant rubber insulation. Built-in internal resistance (16K ohms per meter) functions to suppress radio static and eliminate interference with computerized components and sensors.
