Ignition Cable: Description and Operation

PURPOSE
Conduct high voltage from the ignition coil and deliver to each spark plug in proper sequence.

CONSTRUCTION
Secondary ignition 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 suppress radio static and eliminates interference.
