How Often Should the Factory Spark Plugs Be Replaced on the 10th-Generation Civic?

[McBriella]

The factory spark plugs for the 10th-generation Civic should be replaced every 100,000 kilometers. The standard for the factory spark plugs in the 10th-generation Civic is typically characterized by the heat range, which represents the thermal characteristics of the spark plug. The heat range indicates the balance between heat absorption and dissipation in the insulator nose of the spark plug. A higher heat range signifies a stronger balance between heat absorption and dissipation. Hot-type spark plugs have a lower heat range, while cold-type spark plugs have a higher heat range. Spark plugs are a crucial part of the engine's ignition system, primarily responsible for introducing the high voltage from the ignition coil into the engine cylinder, generating a spark across the electrode gap to ignite the air-fuel mixture inside the engine, thereby providing power to the vehicle.
