Spark Plug Wires is used in GMC Sierra vehicles to complete the ignition circuit so as to send electrical current from this ignition coil to the spark plugs to fire the fuel-air mixture inside the engine cylinders. Closely related to HT leads, these cables are crafted with thick and heat resisting insulation frequently used by electricians to avoid arcing and for added longevity. Today's OE Spark Plug Wires, for the most part, are pre-measured to exact length and incorporate metals at the terminal ends for enhanced contact and integration of technologies that eliminates rf interference. While older engines may have coil wire newer engine have coil packs or individual ignition coils, which are typically screwed on spark plugs directly eliminating the old Spark Plug Wires. It should noted that these wires should be maintained correctly and placed appropriately to facilitate the appropriate running and increased life of the engine.
