Ignition Cable: Description and Operation
SPARK PLUG CABLE
Spark plug cables are sometimes referred to as secondary ignition wires.
The spark plug cables transfer electrical current from the ignition coil(s) and/or distributor, to individual spark plugs at each cylinder. The resistive
spark plug cables are of nonmetallic construction. The cables provide suppression of radio frequency emissions from the ignition system.
