The air conditioning filter of the Qashqai is located near the left foot of the front passenger seat. There is a clip that can be pulled out. Be careful to press gently in the direction of the car's front when removing it to avoid breaking it, and then you can remove and replace it. The Qashqai is the first product designed by Nissan's European Design Center, positioned between a compact SUV and a hatchback. Unlike other crossovers that are directly produced on sedan platforms, the Qashqai is a product specifically designed by Nissan for this unique market segment. From the beginning of its design, the Qashqai has integrated multiple functions, combining the characteristics of SUVs and sedans, optimizing and balancing aspects such as the vehicle's exterior, interior, handling, and comfort to build its core product strength.

Having driven the Kuga for five or six years, I believe whether to change the spark plugs depends on driving habits and vehicle condition. The official manual recommends replacing them roughly every 30,000 kilometers or three years. However, for drivers like me who frequently drive in the city with lots of traffic congestion, spark plugs wear out faster, so it's best to check them every 20,000 kilometers. Last time, I forgot to replace them until 40,000 kilometers, and I noticed engine shaking and increased fuel consumption upon starting. After changing them, the engine ran much smoother. The type of spark plug also matters: copper ones are wear-resistant but have a shorter lifespan, while ruthenium ones last longer. I suggest having a mechanic do a quick check during regular rather than waiting until the car stalls. Personally, I keep an eye on the odometer and replace them at 35,000 kilometers to avoid future issues.

As someone who has repaired many Escapes, the spark plug replacement interval is typically between 20,000 to 30,000 kilometers. The specific frequency depends on the model: the 1.5T turbo engine recommends earlier replacement, such as every 25,000 kilometers, because spark plugs are prone to carbon buildup under high temperatures. You can use a diagnostic tool to check the ignition signal: if the gap is too wide or the color turns black, it indicates replacement is needed. Under normal circumstances, inspect and maintain every 2 years to save fuel and protect the engine. If owners replace them themselves, just choose matching high-quality spark plugs, but beginners should not tamper randomly to avoid damaging the wiring.

Spark plug lifespan is quite important for Escape owners, with the standard being replacement every 30,000 kilometers or 3 years. However, if you frequently drive in traffic congestion or idle often, spark plugs wear out faster and may need replacement every 2 years. Symptoms include difficulty starting or weak acceleration. During regular , have the technician check the spark plug condition and clean any carbon buildup. Using long-life spark plugs can extend the interval to 60,000 kilometers, saving both money and hassle.

That time my Escape reached 35,000 kilometers without changing the spark plugs, and the engine would shake when starting up—I thought it might need major repairs. Upon inspection, the spark plugs were heavily carbon-fouled, and after replacing them, the car felt like new. Generally, it's recommended to change them every 30,000 kilometers, but for those who do a lot of highway driving, you can stretch it a bit longer. DIY replacement is simple and economical, costing just over 100 yuan for parts; if you're not confident, a professional mechanic can do it in about half an hour. Remember, regular replacement prevents emission issues and reduces repair costs.

For the Kuga's spark plug replacement, the core recommendation is every 30,000 kilometers or 3 years. However, adjustments should be made based on engine design and driving conditions: for example, the 1.5T engine suggests replacement within 30,000 kilometers to avoid ignition failures under high load. The choice of spark plugs affects the cycle—double iridium models can last up to 60,000 kilometers. DIY replacement is cost-effective but requires tools; professional service is more reliable. When performance declines, such as sluggish acceleration or increased fuel consumption, inspect immediately. Proper maintenance of spark plugs can enhance overall fuel efficiency and safe driving.
