Read our short guide with information on costs, symptoms and more.

What does a spark plug do?

The engines spark plugs provide the spark in the combustion chamber to detonate the fuel and air mixture in order to force the piston back down and thereby rotate the crankshaft.

How does a spark plug work and what are the components?

The spark plug is screwed into the engine’s cylinder head and protrudes in the cylinder bore. When the engine ECU deems that the piston is in the correct position for the fuel/air mix detonation (timing), it will send a signal to the coil pack that controls the voltage feed to the spark plug. The coil then amplifies the voltage and sends it to the spark plug and forces an electric arc to occur between the electrode and the earthing body of the plug.

This arc (spark) ignites the fuel.air mixture and causes an explosion which forces the piston back down and thus rotating the engine.

How do you know when there is something wrong with a spark plug?

The main symptoms that can occur when there is a faulty spark plug are;

  • When starting the car is problematic.
  • When the engine cuts out after starting.
  • When the engine does not run smoothly (the engine misfires).
  • When the car vibrates excessively.
  • When the 'Check Engine' light on the car's dashboard is on.

When should you consider replacing a faulty spark plug?

Spark plugs are critical to the smooth running of an engine. Without them, the engine will simply not work as it should, if at all. Therefore as soon as you are advised that the spark plugs need changing, you should do so. Running an engine with a faulty spark plug can also cause additional wear and tear on other items.

Spark plugs are always replaced as a set and not done individually.

How can I extend the life of my spark plugs?

The only thing you can do in reality is to use good fuel as this will improve the combustion and prevent the build up of deposits.

Manufacturers service schedules for spark plug changes should be adhered to all tie to prevent issues from arising with older plugs.

What happens during a spark plugs replacement?

  • Mechanic will read the ECU for possible fault codes related to the ignition system.
  • Mechanic will inspect the ignition system and spark plugs.
  • If necessary, the mechanic will replace the full set of spark plugs
  • Mechanic will advise if any other parts need to be replaced.
  • Mechanic will check if the ignition system works correctly again and will test drive the car.
