When the car went to do the second guarantee for more than 18,000 kilometers, the person in the 4S store said that the air filter element of the car was already so dirty and said that he would replace it and give me a rebuff. You can’t change the air filter element in a 4S store without four or five hundred. I am thinking about how the air filter element is so easy to get dirty, which may be related to the fact that Shenzhen is now a city of digging. The road is excavated repeatedly all the time, and the road is naturally dusty.
During the Singles Day holiday, it is a good time to get the air filter element, and all the major online shopping platforms have seen it. The original factory, a certain man and a certain horse have all seen that the price ranges from more than 200 to 80. It turns out that I have always wanted to change the KN air filter element to try. KN is expensive but can be reused after washing. In this way, compared with changing the air filter element for 20,000 to 30,000 kilometers, the money for changing the air filter element can be saved after 100,000 kilometers. Finally, a KN air filter was purchased at a cat KN flagship store for 618.
After receiving the express delivery at an interval of three or four days, there is no problem when it is opened and checked. Choose to install the air filter yourself on Saturday. A4L air filter element is not troublesome to disassemble and assemble.
Tools: T20 clubs screwdriver and a word screwdriver. Just use the screwdriver in the car tool.
After the replacement of the KN air filter element, the feeling of driving in the past three or four days is still good, especially at the start and low speed, the low torsion performance of the car is still greatly improved. Start a little brisk, low-speed refueling is the power to come more directly. Medium-speed big foot throttle overtaking power performance is more straightforward. As for saving fuel and preventing the engine from accumulating carbon, the fuel consumption seems to be about the same as before. Personal suggestion: if you want to change the KN air filter element, don’t hesitate to buy it. It’s almost double twelve, and I have to buy a special cleaning suit for KN filter elements. In the future, I am going to wash the air filter element for ten thousand kilometers by myself, so that the engine can breathe more and cleaner air.

Twist the screw and pull the screw out. Screw seems to be limited position can not be completely pulled out, may be to prevent the loss of the screw.
The sensor connector of the air filter element needs to be unplugged. Remember to push the white buckle off and pull it out easily.
Dismantling
The old air filter element has leaves, but it is not very dirty. It’s no problem to blow a high-pressure air gun and run more than 10,000 kilometers.
4S took apart and looked at my air filter element, and asked me to replace it when I saw it dirty. I didn’t agree to replace them, and they wouldn’t help blow the dust and leaves with a high-pressure air gun. We can only pay attention to the 4S store, let’s keep an eye on it when we go to the 4S store for maintenance.
There are small leaves and a lot of dust in the intake chamber of the air filter element. In particular, the top of this sponge is dirty. I specially took it out and patted it.

Plug in the air filter sensor to check whether it is tight, and finally be sure to push the white buckle in place.
If you don’t plug in the car, the computer will call the police.
The old one is not very dirty, since I bought a new KN, I can only retire it.
Reset complete.
For the record, the car is still very fuel-efficient.
Finally, it was unexpectedly found that the A4 original air filter element was imported from Germany. It seems that FAW still has a little conscience that this air filter element is actually imported from Germany.
