Understand What Influences Spark Plug Lifespan

Although spark plugs naturally get dirty and eventually need to be replaced, there are some factors which can speed up their degradation. These include:

  • Aggressive driving with heavy acceleration
  • Lots of stopping and starting within short periods
  • Failing to replace engine oil promptly
  • Not scheduling regular engine maintenance
  • Exposure to extreme temperatures

Follow the Recommended Service Intervals

Your local dealership can advise you how often the spark plugs need to be changed on your Ford. As well as considering factors such as your typical driving conditions, they will also be guided by the type of spark plugs you have:

Copper Spark Plugs

A copper and nickel alloy is the most common type of spark plug and is an excellent conductor of electricity. However, as copper is a relatively soft metal, this type of spark plug tends to wear more quickly and needs to be replaced every 2–3 years, or 20,000–30,000 miles.

Platinum Spark Plugs

Platinum doesn’t conduct electricity quite as well as copper, but is still effective enough for spark plugs. What it lacks in sparking performance, it makes up for in lifespan because platinum plugs typically last 4–7 years, or 60,000–100,000 miles.

Iridium Spark Plugs

Iridium combines the best of copper alloy and platinum, delivering outstanding performance and impressive longevity. It also has the added benefit of having a lower melting point than both other metals. If you have iridium spark plugs, you can expect them to last around 5-9 years, or 75,000-125,000 miles, possibly longer.

Be Alert for Warning Signs

As well as understanding the recommended routine maintenance, it’s also important to look out for any warning signs that your spark plugs are struggling. This might include:

  • Misfiring engine
  • Rough idling
  • Reduced fuel economy
  • Backfiring or sputtering
  • Difficulty starting

Schedule Regular Maintenance Services

By taking your car for regular maintenance services at your local dealership, any required repairs can be carried out promptly. This prevents other engine problems from causing your spark plugs to degrade.
