Ignition Wire Set Replacement

Mobile Ignition Wire Set Replacement at Home or Office

If your spark plug wires have been in use for a while, they can develop resistance, hindering the efficient transfer of electric pulses. This resistance often arises from contact corrosion or deterioration of the insulated coating on the wires. Cracks or tears in the insulation can lead to electric pulses arcing to other engine parts, resulting in misfires. Additionally, corroded terminals can cause a loss of electrical power, leading to incomplete combustion of the fuel-air mix in the cylinder. Incomplete combustion can manifest as engine misfires, rough idling, power loss, or even emission issues, potentially causing your vehicle to fail inspections. Misfires or emission problems may also trigger the check engine light.

What is Ignition Wire Set Replacement?

Ignition wire set replacement involves replacing the aged or faulty spark plug wires that connect the distributor or ignition coil to the spark plugs. These wires transmit the high voltage spark needed for combustion, typically consisting of a copper wire core wrapped in a thick insulating material. Each end of the cable features a clip to securely attach it to a spark plug or coil, preventing loosening due to engine vibration.
