Spark Plug Wire: Description and Operation

PURPOSE

The secondary wires carry voltage between the ignition coil, distributor, and spark plugs. The secondary wire connections form a tight seal that
prevents voltage arching.

CONSTRUCTION

Spark plug wiring has an outer layer of silicone. The silicone spark plug boots form a tight seal on the plugs and the distributor cap.
