Read our short guide with information on costs, symptoms and more.
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.
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.
The main symptoms that can occur when there is a faulty spark plug are;
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.
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.
The cost of replacing the spark plugs depends on your car and what parts your car's manufacturer recommends using for the replacement. Find out what you could save by having the spark plugs replaced by ClickMechanic, by selecting your car at the top of this page!
