A vehicle engine requires a precise quantity of air and fuel in order for the engine to operate. Air enters the system initially by means of an air filter. The air filter’s function is to strain out dirt and other contaminants in the air, hindering those particles from getting inside the system and causing harm. Usually, the air filter is bound to the intake manifold by means of a big plastic tube through which the air circulates.

The air filter is basically made from a material similar to paper, or any fibrous element, all folded up like an accordion and set on a plastic or metal base to match the air filter holder of your vehicle. Air filters can also be designed from cotton or certain fabric-like materials, which are oiled for maintenance, and to amplify airflow throughout the filter.
