Replacement procedure of automobile air filter
The first step is to open the engine compartment cover and confirm the position of the air filter. The air filter is generally located on the left side of the engine compartment, above the left front wheel. A square plastic black box can be seen and the filter element is installed inside. There are 4 clips around the housing cover, which are used to press the plastic housing above the air filter to keep the air inlet pipe sealed. The structure of the buckle is relatively simple. We can lift the upper cover of the entire air filter by gently lifting the two metal clips upwards. Some models also use screws to fix the air filter. At this time, you need to select an appropriate screwdriver to unscrew the screws on the air filter box to open the plastic housing and see the air filter inside.

Step 2: Take out the air filter element and check whether there is much dust. Tap the end face of the filter element gently, or use compressed air to clean the dust on the filter element from the inside out. Do not wash it with tap water. If the air filter is seriously blocked, replace it with a new one.

The third step is to thoroughly clean the air filter box after handling the air filter element. Generally, a large amount of dust will accumulate under the air filter, which is the culprit of engine power decline.

Step 4: When installing the new air filter, we need to pay attention to a protruding plastic sheet on the right under the air filter. This plastic sheet is designed to prevent the air filter from being installed reversely. When installing the air filter, it is necessary to clip the plastic sheet into the slot of the filter base before installing it in place. After confirming that the air filter is installed in place, the shell can be covered, and the four clips at the edge are buckled to complete the work.
