I've changed the air cabin filter for my 408 several times by myself. First, locate the glove compartment, open it, and press the clips on both sides to easily remove it. Then you'll see the cover plate—use a small screwdriver to loosen the fixing screws and pull out the old filter to replace it with a new one. Just use a common household Phillips screwdriver; no professional tools are needed. The whole process takes about 15 minutes and costs just a few dozen yuan, while ensuring fresh air inside the car. Especially during spring and autumn when pollen is abundant, frequent replacement can reduce allergy issues. I usually change it every six months—making it a habit is great for health and saves hundreds of yuan compared to doing it at a 4S shop. The key is to avoid using excessive force that could damage the clips; be gentle during disassembly and installation.
As someone who frequently works on cars, the key to replacing the 408's cabin air filter lies in the tools and method. You'll need a T20 screwdriver, located on the right side inside the glove box. After removing the glove box, take off the cover plate and remove the old filter to compare and select a new one of the same model. Don't mix up the steps: first disconnect the car's power to prevent short circuits, and when installing the new filter, ensure the arrow direction is consistent to guarantee proper airflow. A common mistake is installing the filter backward, which can lead to reduced airflow or strange noises, and may also cause the filter material to deform and shorten its lifespan. Remind owners to check and replace it every 10,000 kilometers or once a year, and consider keeping an activated carbon filter on hand to enhance purification performance. During the process, pay attention to the durability of the clips and protect the interior as a detail. In short, doing it right ensures both safety and savings.
I used to find replacing the 408's cabin air filter super easy. Just open the glove box, press the clips to remove it, and the filter cover is right there. Unscrew it, swap in the new filter, and you're done—takes barely 10 minutes. Buying filters online costs just 20-30 yuan, DIY saves both time and money. Key is picking the right model to avoid mistakes, then test airflow after installation. This maintenance improves cabin air quality, preventing odor buildup.
