Ignition Cable: Service Precautions

Silicone spark plug boots form a tight seal to the spark plugs. The boot should be twisted 1/2 turn while removing. DO NOT pull on the wire to remove it from a spark plug. Pull on the boot, or use a tool designed for this purpose. Care should also be exercised when connecting a timing light or other pick-up equipment. DO NOT force anything between the boot and wiring, or through the silicone jacket. Connections should be made in parallel using an adapter.
