What is the replacement interval for spark plugs in the 10th-generation Civic?

The replacement interval for spark plugs in the 10th-generation Civic is 40,000 to 60,000 kilometers. Prolonged failure to replace spark plugs may result in decreased vehicle power and increased fuel consumption. Commonly referred to as spark plugs, their function is to discharge the high-voltage pulses delivered by the high-voltage wires (spark plug wires), creating an electric spark that ignites the air-fuel mixture in the cylinder by breaking down the air between the two electrodes. The 10th-generation Civic is a compact sedan launched by Honda, with dimensions of 4649mm in length, 1800mm in width, and 1416mm in height, and a wheelbase of 2700mm. It is equipped with either a 1.0T or 1.5T turbocharged engine, paired with a CVT transmission.
As a seasoned driver with over a decade of experience, I remember changing the spark plugs for the 10th-gen Civic later than recommended. The manual suggests replacing them around 100,000 km. For city driving like mine, with frequent starts at traffic lights causing faster wear, it's advisable to check them at about 70,000 km. Once, when I drove up to 90,000 km, the engine started shaking. A check revealed the spark plug electrodes were eroded. After replacement, acceleration became smoother and fuel consumption dropped. I recommend having the mechanic check the gap during maintenance before the warning light comes on, as delayed replacement can affect ignition efficiency and potentially damage the coil, leading to costlier repairs. Also, if you smell unburned gasoline while driving, it's a sign to address the issue promptly.
