Why Replace Spark Plugs at 60,000 km If Everything Feels Fine?
Many motorists wonder why they need to replace spark plugs at 60,000 kilometers when their vehicles still seem to run normally

Many drivers notice that their vehicles continue to run normally even after traveling 60,000 kilometers without replacing their spark plugs. This common observation raises a frequent question among motorists: if nothing seems wrong with the vehicle's operation, why is it necessary to bother changing the spark plugs at this interval?[1][2]
According to automotive insights, the short answer is that spark plug performance degradation happens gradually over time. Because this decline in efficiency is slow and incremental, it makes it difficult for drivers to notice the loss in performance during daily driving.[1]
