How do you change the spark plug wire?
Before installing the boot on to the spark plug, add a small amount of dielectric grease to the spark plug boot. The boot will be fully seated onto the plug when a small click is felt. Plug wires run from the distributor or coil to the plug, and must be replaced exactly as factory run.
When do you need to replace spark plugs?
The engine symptoms can also be caused by faulty spark plugs and other, deeper issues, so you first must prove that your wires have gone bad and need to be replaced. You may need to replace the wires if you see sparks jump to the ground at night with the hood up and engine running.

What to do when your spark plug goes out?
Grasp the rubber boot firmly. If it doesn’t pop off immediately, try twisting it back and forth while you pull it free. Inspect the boot for signs of carbon tracking. This will appear as a black line running from top to bottom inside the boot. If you notice this line, the spark plug must be removed for inspection. Helpful? Work backward.
How do you replace a spark plug wire?
Spark plug wire replacement tip: To remove spark plug wires from the plug without damaging the boot or wire, use a spark plug boot puller tool instead of a pliers. Click here to see the tool I recommend Alldatadiy.com and Eautorepair.net are professional-grade shop manuals—period.
What are the symptoms of bad spark plug wires?
This is necessary due to the aging of the spark plug wires from exposure to extreme temperatures (hot and cold), engine chemicals (oil, grease, coolant, etc.) and electrical stresses. Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency.
What kind of spark plug wire do you need?
If your vehicle came with MAG wires, you MUST replace them with the same type. The third type of spark plug wire is the fixed resistor style. They’re made with a steel or copper core and a resistor located in the spark plug boot.
How often do spark plug wires need to be changed?
Average rating from 253 customers who received a Ignition Cable (Spark plug wires) Replacement. Spark plugs provide the electricity necessary for combustion to happen by igniting atomized fuel in an engine’s cylinders. However, they need a constant supply of electricity to do that. This is the job of your spark plug wires.
Why do spark plugs have too much resistance?
Due to the high voltage constantly sent through the spark plug wires, they have the tendency to increase in resistance over time. Eventually, this creates too much resistance for any electricity to flow.

Do you need an ohmmeter for spark plugs?
You’ll need an ohmmeter for this, and you’ll need to know what the wires’ original resistance was. Test each wire and look for resistance levels higher than when originally installed, as well as higher resistance in individual wires (which indicates a failed wire).
