What is an Air Filter in Car?
The air filter in a car is usually located inside a rectangular or cylindrical airbox near the engine, often on top or to the side, depending on the vehicle model. It's easy to access by simply popping the hood and removing the airbox cover, which is usually held by clips or screws.
The air filter's primary job is to keep dust, dirt, and debris from entering the engine. This is important because a clean air filter ensures that only clean air reaches the engine, which improves combustion, fuel efficiency, and overall performance. A dirty or clogged air filter can restrict airflow, leading to reduced engine power, lower gas mileage, and increased emissions. Regularly checking and replacing the air filter helps maintain engine health, prevents costly repairs, and keeps your car running smoothly.
