How Long Does an Ignition Cable (Spark plug wires) Last?

ignition cable

The ignition of a car is an essential part of a good running engine. Each time that you turn the key of your car over to crank it, the ignition wires will have to transfer the electricity from the ignition coil to the spark plugs. This will help to get the combustion process started. Without properly working spark plug wires, your engine will be able to fire like it is supposed. Due to the constant use that the spark plug wires on a car gets, they will wear out over time and can cause a variety of different issues.

The ignition cables on a car are made to last about 60,000 miles before they have to be replaced. In some cases, the wires will need to be replaced due to the rubber boots on the end getting damaged and now allowing for a good connection with the spark plugs. Taking the time to give the wires an inspection from time to time to see if there is any damaged. Spotting problems with the ignition wires early on can save you a lot of time and money in the long run.

In most cases, you will begin to notice that the car is running sluggishly when the ignition wires are in need of replacement. Rather than having your car running badly, you will need to take the time to find out what is wrong with it. Usually, the check engine light of the car will come on. This means that you can take it into a mechanic and have the use OBD tool to find out why the light is on.

Here are some of the other things you will notice when it is time to replace your ignition wires:

  • The engine misfires on a regular basis
  • The gas mileage on the car is significantly lower
  • The engine shakes when trying to take off
  • The car will not crank or takes a long time to crank

When you start to notice these warning signs, you will have to make sure that you address the repairs needed in a hurry. Having your damaged ignition wires replaced by a professional can take away a lot of the stress that comes with these repair situations.
