Spark Plug Wire: Description and Operation
The spark plug wiring used with the ignition system is a carbon impregnated cord conductor encased in a 7 mm (9/32 in.) diameter silicone rubber
jacket. The silicone wiring will withstand very high temperatures and also provides an excellent insulator for the higher voltage of the ignition system.
The silicone spark plug boots form a tight seal on the plug and the boot should be twisted 1/2 turn while removing. 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. Pull on the boot, or use a tool designed for this purpose.
