How long do plug wires last?

How long do plug wires last?

around 60,000 to 70,000 miles

How can you tell if a plug wire is bad?

Signs and symptoms of bad spark plug wires

1. Hard starting.
2. Engine misfire.
3. Engine hesitation.
4. Engine surging.
5. Engine rough idling.
6. Reduced engine power.
7. Check engine light.

Can I change my spark plugs without changing the wires?

It is not necessary to change the wires but it’s a good idea. Here’s the reason. If your spark plugs have been in the engine too long the component at the end of the plug get’s oxidized over time from having such high voltage run across it to jump a gap and create a spark.

What happens if you don’t change spark plugs and wires?

Spark plugs will deteriorate over time, so if they are not replaced, various engine issues will arise. When the spark plugs do not spark adequately, the combustion of the air/fuel mixture becomes incomplete leading to loss of engine power, and in the worst case scenario the engine will not run.

Is it bad to only change half the spark plugs?

But, your engine will only be as strong as its weakest component, eventually old spark plugs will become covered in oil deposits, foul up and cause incorrect firing or intermittent misfiring from being unable to ignite the gasoline. And fixing only half of the spark plugs wont stop it.

Do spark plug wires wear out?

And, just like your plugs, the wires wear out over time. Once they begin to wear, the electrical charge sent to the spark plugs can be unreliable, which creates problems with engine operation, including rough idling, stalls, and other issues.

What can faulty spark plug wires cause?

If there is any issue with the spark plug wires the engine spark can be disturbed, which can result in engine performance issues such as misfires, a reduction in power and acceleration, as well as a reduction in fuel efficiency. In severe cases bad cables may even result in engine stalling.

How long do spark plug wires last years?

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. Probably 6–10 years.

How many years do ignition coils last?

Life Span. Federal law in the United States dictates that the ignition coil and ignition module on new vehicles are warranted for at least two years or 24,000 miles, whichever occurs first. The insulation in the ignition coil will degrade over time, but many coils are designed to last 100,000 miles or more.

Which spark plug is better iridium or platinum?

Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
