Why Replace Spark Plugs?

[Eden]

Reasons for replacing spark plugs: Spark plugs have a service life and can accumulate carbon deposits over prolonged use. If not replaced regularly, the engine may experience difficulties starting, insufficient power, increased fuel consumption, and excessive exhaust emissions. If a spark plug fails, the car cannot operate normally and requires immediate replacement. The replacement interval for spark plugs typically ranges between 20,000 to 100,000 kilometers, varying based on the material. Ordinary nickel-alloy spark plugs should be replaced every 20,000 to 30,000 kilometers, while platinum spark plugs can last 60,000 to 80,000 kilometers before replacement. If abnormal engine vibrations occur during acceleration, it is likely due to degraded spark plug performance. Deteriorating spark plugs significantly reduce the engine's ignition efficiency, leading to sluggish acceleration.
