The main air filter removes contaminants from the air that goes into your engine. It is part of the vehicle’s air intake system and it removes water, dirt, pollen, bugs, and any other debris that comes through your vehicle’s grill. The air filter should be checked during every oil change and should be replaced when it is dirty. When the air filter gets dirty, the engine will not breathe properly. In extreme cases, it can cause decreased gas mileage, strange engine noises, reduction in horsepower, or the check engine light to come on.
