Ignition Cable: Description and Operation
SPARK PLUG CABLES
Spark plug cables are sometimes referred to as secondary ignition wires. These 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.
