Disconnect the negative terminal of the battery and remove the engine cover. Unscrew the first spark plug cap. At the bottom of the well, you will find the spark plug.

Before proceeding with the removal, clean the area thoroughly with compressed air. Using a 16 mm spark plug socket, gently insert it onto the spark plug head and unscrew it. Be careful not to drop any foreign objects into the well. Replace the spark plug with one of the same model, carefully inserting it into the well and turning it gently to ensure it screws in correctly.

If you encounter resistance, remove it and try again. The spark plugs should be tightened with a torque wrench; if you do not have one, tighten them without overdoing it. Repeat the same process for the other spark plugs.
