Spark Plug Wire: Description and Operation
The spark plug wire harness assemblies use carbon impregnated cord conductors, encased in 8 mm (5 / 16-inch) diameter silicone jackets. The silicone
jackets withstand very high temperatures and also provide excellent insulation for the high voltage of the system. Silicone spark plug boots form a tight
seal to the spark plugs.
The material used to construct spark plug wires is very soft. This wire will withstand more heat and carry a higher voltage, but chaffing and cutting
become easier. The spark plug wires must be routed correctly to prevent chafing or cutting. When removing a spark plug wire from a spark plug, twist
the boot on the spark plug one-half turn while pulling on the boot.
