A vehicle air filter is an essential component of a car’s intake system that traps dust, dirt, and other airborne particles before they enter the engine. By ensuring clean airflow, it helps improve engine efficiency, enhances fuel economy, and reduces emissions. Air filters are typically made from paper, foam, or cotton and come in different designs, such as panel, cylindrical, or conical filters. A clean air filter promotes better combustion, prolongs engine life, and prevents damage caused by contaminants. Regular replacement or cleaning of the air filter is necessary to maintain optimal vehicle performance and engine health.
