How often should the spark plugs be replaced on a Changan Honor?
3 Answers
Changan Honor spark plugs should be replaced every two years or 60,000 kilometers. The function of spark plugs is to discharge the pulsed high-voltage electricity delivered by the high-voltage wires, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the mixed gas in the cylinder. The types of spark plugs include: 1. Standard spark plugs; 2. Insulator-protruding spark plugs; 3. Electrode spark plugs; 4. Seat-type spark plugs; 5. Pole-type spark plugs; 6. Surface-gap spark plugs. Taking the 2020 Changan Honor as an example, it is equipped with a 1.5L naturally aspirated engine, with a maximum horsepower of 107 PS, a maximum torque of 145 Nm, and a maximum power of 78.5 kW. The body dimensions of the 2020 Changan Honor are: length 4450 mm, width 1685 mm, height 1835 mm, with a wheelbase of 2750 mm.
As a Chana Ono owner, spark plugs are generally replaced every 30,000 to 40,000 kilometers, but this depends on your driving habits. From my experience, frequent city traffic congestion accelerates spark plug wear, so it's best to have a mechanic inspect them every 25,000 kilometers. If your car starts shaking, fuel consumption suddenly increases, or you experience difficulty starting the engine, it's likely time to replace the spark plugs. Delaying replacement can affect engine performance and increase repair costs. Don't skimp on maintenance—original spark plugs cost just a few dozen yuan per set, and a replacement can last several years. If you frequently drive long distances on highways, you can extend the interval slightly, but safety comes first. Don't wait for problems to arise before taking action, as a breakdown could ruin your driving experience.
For car maintenance, I recommend replacing the spark plugs for the Changan Ono every 40,000 kilometers. The engine design tends to cause carbon buildup on the spark plugs, especially with frequent short trips. If not replaced in time, you may notice unstable idling, difficulty starting when cold, and a significant increase in fuel consumption. When checking them yourself, remove the spark plugs to inspect if the electrodes are eroded or the gap is too wide—replace them early if any issues are found. Using the correct model can extend their lifespan; they might last up to 50,000 kilometers with more highway driving, but don’t push your luck. Regular maintenance is key—failing spark plugs can turn minor issues into major problems, affecting the overall reliability of your vehicle.
