How often should the Nissan air filter be replaced?
2 Answers
Nissan air filters are typically replaced every 20,000 kilometers. For vehicles that frequently drive on highways, the replacement interval can be extended to 30,000 kilometers. The air filter, also known as the air cleaner, is primarily required to have high filtration efficiency, low flow resistance, and the ability to operate continuously for extended periods without maintenance. The air filter ensures that the air entering the engine for combustion is relatively clean, thereby reducing engine wear. Taking the Qashqai as an example, this vehicle is a compact SUV under Dongfeng Nissan. It measures 4401 mm in length, 1837 mm in width, and 1593 mm in height, with a wheelbase of 2646 mm. In terms of power, the Qashqai is equipped with a naturally aspirated engine that delivers a maximum horsepower of 151 PS, a maximum torque of 194 Nm, and a maximum power output of 111 kW.
I've been driving Nissan cars for over a decade, and it's recommended to replace the air filter every 15,000 kilometers or annually. Since I often drive in urban areas with heavy dust and smog, if I don't change the filter in time, the engine's air intake can get blocked, potentially causing fuel consumption to spike by 10% and reducing power. Regular checks are simple: open the engine hood, open the air filter box, and visually inspect if the filter is dusty or blackened—replace it immediately if it's dirty. Don't cheap out on counterfeit filters; just buy an OEM or genuine one. If you usually drive in suburban areas, you can delay replacement slightly, but exceeding 20,000 kilometers without changing it can damage core engine components, leading to higher maintenance costs. Make it a habit to replace it yourself—it's clean, quick, and saves money.
