Why Do Spark Plugs Need to Be Replaced?

[McEverett]

Reasons for replacing spark plugs: If spark plugs are damaged, they can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal use of the vehicle. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the instructions in the user manual. Steps for replacing spark plugs: Open the engine hood and lift the plastic cover of the engine. Remove the high-voltage wires and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plugs into the spark plug holes and hand-tighten them a few turns before using the socket to tighten them further. Reinstall the high-voltage wires according to the ignition sequence and secure the cover.
