How often should the spark plugs of the Qashqai be replaced?
3 Answers
The spark plugs of the Qashqai should be replaced every 100,000 kilometers. However, the actual replacement interval should be determined based on the vehicle's usage conditions and any fault symptoms that may arise. It is recommended to replace them when issues such as poor ignition or insufficient power occur. Spark plugs are a crucial component of the gasoline engine's ignition system, as they introduce high voltage electricity into the combustion chamber and create a spark across the electrode gap to ignite the air-fuel mixture in the cylinder. The Qashqai is a model under Dongfeng Nissan, with body dimensions of 4315mm in length, 1783mm in width, and 1606mm in height, and a wheelbase of 2630mm. In terms of exterior design, the Qashqai combines the best features of high-end hatchback cars with the design styles of SUVs and HBs, resulting in a fashionable and avant-garde overall appearance with modern, flowing body lines.
I drove a Nissan Qashqai for over six years. According to the maintenance manual, the spark plugs are recommended to be replaced every 60,000 kilometers or five years, but it really depends on how you use the car. If you frequently encounter city traffic jams with constant engine start-stop cycles, the spark plugs wear out faster and may need replacement before hitting 60,000 km. Once, I delayed replacement until 70,000 km, and the engine started shaking, had difficulty starting, and consumed more fuel. Upon inspection, the spark plugs were found to be severely eroded—replacing them immediately restored smooth performance. Nowadays, Qashqais are common in the used car market, and neglected spark plugs can negatively impact resale value. I recommend checking the spark plugs during routine maintenance—if the gap is too wide or there’s heavy carbon buildup, it’s time to act. In short, don’t wait until major engine issues arise. Prioritizing this ensures safety and peace of mind—a key point all Qashqai owners should keep in mind.
As a Qashqai owner for several years, I find spark plug replacement really cost-effective. Generally, it's done every 60,000 kilometers at a low cost of just a few hundred yuan. But skipping it can backfire—last time I neglected it, my fuel consumption jumped by 15%, costing more on gas and nearly requiring ignition coil repairs. Remember, the Qashqai's engine relies on spark plugs for ignition; reduced efficiency means weaker performance. If your car is over 5 years old or frequently used for long highway trips, spark plugs wear out faster and should be checked sooner. Related maintenance like throttle body cleaning should also be done to avoid chain reactions. Follow the manual and develop good habits to keep your car running well for years.
