Replace the engine air filter
更换发动机空气滤芯
A common tool-light service, provided the owner manual shows an accessible air-box and the exact filter orientation.
若手册明确显示空气滤盒位置和滤芯方向，这是常见且工具需求较少的保养项目。
Beginner · 10–20 min · Correct filter, basic screwdriver if required
1. Confirm the part
Match the filter by VIN, model, engine and year. Compare the new part with the old before discarding packaging.
确认配件
按车架号、车型、发动机和年份匹配滤芯；拆包装后先与旧件对比。
2. Open only the air-box
Engine off and cool: release the marked clips or screws. Do not unplug sensors or pull hard on intake hoses unless the manual requires it.
只打开空气滤盒
发动机熄火冷却后，打开指定卡扣或螺丝；除非手册要求，不要拔传感器或用力拉扯进气管。
3. Clean without contamination
Lift out the filter, note airflow/orientation, and wipe loose dust from the box with a damp lint-free cloth. Do not let debris fall into the clean-air side.
清洁但不污染
取出滤芯并记住气流方向；用微湿无绒布擦除滤盒灰尘，避免杂物落入洁净侧。
4. Seat and close
Place the new seal flat with no folded edges, close all clips/screws and check the intake hose remains secure.
正确安装并关闭
让新滤芯密封边平整、无折叠，再扣紧全部卡扣或螺丝，并确认进气管牢固。
