The Sylphy's air filter is located in the air cleaner on the engine intake pipe. The Sylphy is a compact family sedan produced by Nissan. Taking the Sylphy 2021 Classic 1.6XE Manual Comfort Edition as an example: this model is equipped with a 1.6L 122 horsepower L4 naturally aspirated engine paired with a 5-speed manual transmission, delivering a maximum power of 90 kW and a maximum torque of 155 N·m, with a top speed of 188 km/h. The Sylphy 2021 Classic 1.6XE Manual Comfort Edition has body dimensions of 4631 mm in length, 1760 mm in width, and 1503 mm in height, with a wheelbase of 2700 mm. Its front suspension is of the MacPherson strut independent type, and the rear suspension is a torsion beam non-independent type.

The air filter of the Sylphy is located in the engine compartment, and its position is quite easy to find. Open the hood, stand directly in front of the car and look towards the right front wheel, you'll see a black rectangular plastic box, slightly larger than the palm of your hand, usually secured with clips or screws. Last time I replaced it, I noticed the box was right next to the battery, and lifting the cover reveals the air filter inside. Remember to wipe the dust inside the box with a wet wipe before replacing it, otherwise the new filter will get clogged up quickly. It's best to replace it every 10,000 kilometers or once a year, especially in dusty areas like the northern regions. I usually buy the filter online and replace it myself—just make sure to get the right model, and it only costs a few dozen yuan, saving half the price compared to the dealership. If you're not keen on doing it yourself, you can ask the mechanic to replace it during regular maintenance.

I've changed the air filter myself several times on my Nissan Sylphy. It's hidden on the right side of the engine bay - just pop the hood and you'll see a black rectangular plastic box located between the windshield washer reservoir and the battery. The box cover has several clips, though some older Sylphy models use screws that require a Phillips screwdriver. The filter itself looks like an accordion-folded paper fan - just match the size and pleat direction when replacing. I change it every 8,000 km because there's lots of construction dust on my commute. The whole process takes about five minutes without even needing gloves. Genuine filters online cost around 30 yuan, with aftermarket ones being even cheaper - way more economical than shop labor fees. Plus, it's a good opportunity to check other hoses for cracks while you're at it.

The air filter location of the Sylphy is quite well-designed. Open the hood and look directly for the rectangular black plastic box on the front right, positioned next to the engine, near the direction of the windshield. The box usually has an intake pipe arrow marked on the side, and you can simply unclip the fasteners by hand to remove the filter. It's recommended to check the filter's condition during every maintenance service. If the pleats are filled with gray-black fibrous debris, it's time for a replacement. Nowadays, purchasing filters online is very convenient—just input your vehicle's model year to match the correct part number. If you're replacing it yourself, remember to clean the accumulated dust at the bottom of the box, as it can affect the engine's air intake efficiency. Long-term neglect of filter replacement may lead to increased fuel consumption, with a particularly noticeable sluggishness when accelerating.
