The spark plugs in a car are a crucial part of the ignition system and represent one of the ignition components of the internal combustion engine. Their role is to produce a spark capable of igniting the compressed mixture from the piston in the combustion chamber.

Clean the spark plugs every 10,000 miles and replace them every 12,500 miles. To find out which type of spark plugs your car uses, consult the owner's manual.

To change them, disconnect the high-tension leads connecting them to the distributor. After disconnecting the leads, clean the areas around the spark plugs.

Use the appropriate socket to unscrew the plugs, and before installing the new ones, check that there is the correct gap between the electrodes.
