How many kilometers the spark plugs of Wuling Hongguang S should be replaced depends on the owner's driving habits. The vehicle maintenance manual will also specify the mileage at which the spark plugs need to be replaced. During maintenance, you can check the spark plugs and replace them if necessary. If the spark plugs are still in good condition during inspection, they can continue to be used without replacement. Spark plugs are wear parts. After prolonged use, the electrode gap will increase, and carbon deposits will appear on the spark plug electrodes. The electrodes of the spark plugs are located in the combustion chamber. After the compression stroke, the spark plugs are responsible for igniting the combustible mixture. The Wuling Hongguang S is equipped with two engines, the PTEC 1.2L and 1.5L, designed and manufactured according to General Motors' global powertrain standards. Both engines feature a double overhead camshaft design, ensuring ample power while also demonstrating good fuel economy, significantly reducing vehicle operating costs.
I've been driving my Wuling Hongguang S for almost three years now, and spark plugs are something you really need to pay attention to. Generally, they should be replaced every 20,000 kilometers, otherwise the car can develop problems. My Wuling gets them changed on schedule - I remember at 20,000 km the engine started gasping and having trouble starting, but it perked right up after getting new plugs. Worn spark plugs can lead to increased fuel consumption, severe engine vibration, and in serious cases might even cause the car to stall mid-drive. Different types of spark plugs have varying lifespans: copper-core ones are cheaper but need more frequent replacement, while iridium ones last longer but cost more. The Wuling Hongguang S owner's manual also recommends this mileage interval. I suggest checking the spark plug gap during regular maintenance to ensure proper ignition quality. If you mainly drive in city traffic with good road conditions, you might stretch it to 25,000 km, but don't exceed 30,000 km - safety first.
I take car maintenance very seriously, and the recommended replacement interval for spark plugs is between 20,000 to 30,000 kilometers. The original spark plugs in the Wuling Hongguang S are mostly copper-core type, which are not very wear-resistant, so they need to be replaced by 20,000 kilometers. If not replaced in time, ignition system failure can lead to increased carbon deposits, causing uneven engine performance and jerky driving. Last time, my neighbor delayed the replacement, and a broken spark plug ended up costing him a lot for engine repairs. Therefore, it's good practice to check the spark plugs during every maintenance: if they appear blackened, it's a sign they need replacement. Iridium spark plugs last longer; although they cost more, they are more reliable. In the end, don't skimp on small expenses to avoid big troubles—replacing them according to mileage is the most dependable approach.
Having driven for most of my life, I know spark plugs well. For the Wuling Hongguang S, changing spark plugs every 20,000 kilometers is a basic rule—any longer and the engine starts protesting. Early on, I tried stretching it to 30,000 kilometers, but ended up with misfiring and difficulty starting on cold mornings. Regular spark plugs are cheap, just over ten yuan each, and easy to replace. This car is tough and durable, but small parts maintenance can't be ignored. Regularly check if the spark plug gap is normal—around 0.8mm is ideal, as anything larger or smaller affects ignition. Misfiring can also damage other components. In short, just like anything else, keeping a car running smoothly depends on consistent, long-term maintenance.
