Your engine produces power by burning a mixture of fuel and oxygen in your combustion cylinders. Each of your cylinders has a spark plug that ignites the mixture with an electric spark. The electricity for that spark travels to your plugs through your Chevy Silverado spark plug wires.

The ignition process is carried out thousands of times while your vehicle is running, so your Silverado spark plug wires have to be in great shape to handle tens of thousands of volts of electricity at a time. This means the silicon jacket surrounding your spark plug wires must be seamless, or the electricity will try to jump the wires.

If cracks or imperfections develop in your Chevy Silverado spark plug wires, you will notice a difference in your engine’s performance. Some of the symptoms of bad Silverado spark plug wires include misfires and detonations, sluggish or rough running, hard starting, lowered fuel efficiency, and fouled spark plugs. You may be able to notice problems with your spark plug wires through a visual inspection, but you will not be able to see cracks in the inside of the jacket or damage to the wires themselves. You should replace your Chevy Silverado spark plug wires with every engine tune-up, and also whenever you install new spark plugs.
