What is the standard spark plug gap?

[CamilleFitz]

The normal gap for a spark plug is between 0.6 to 1.3mm. A larger spark plug gap produces a longer arc during ignition, making it easier to ignite the air-fuel mixture in the cylinder, which naturally results in greater kinetic energy. Steps for replacing spark plugs: Open the hood, remove the engine's plastic cover, and detach the high-voltage distributor wires. 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 external debris like leaves or dust and ensure they are thoroughly cleaned. Insert the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to fully tighten it. Reinstall the high-voltage distributor wires according to the firing order, then secure the cover. If a spark plug is damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty starting the engine, affecting normal vehicle operation. Severe spark plug erosion—such as scarring at the tip, electrode damage, or melting—indicates that the spark plug is ruined and should be replaced.
