An air filter, also known as an air cleaner, is a component that removes dust, dirt, and other contaminants from the air before it enters the engine. Its main function is to protect the engine from damage and improve its performance by providing clean air to the combustion chamber.
It's important to note that air filters should be replaced regularly, as per the vehicle's recommended schedule or as indicated by the vehicle's manufacturer. Neglecting to replace the air filter can lead to reduced engine performance, increased fuel consumption, and increased emissions.
It's also important to use the correct type of filter for your vehicle as specified in the vehicle's manual or by the filter manufacturer.
