Can a dirty air filter affect car performance?

An air filter keeps dirt, debris, contaminants, and road bugs from reaching your engine and ensures an adequate supply of air into the combustion chamber of the engine. Once an air filter is too clogged and no longer working, it can lead to decreased car performance and even engine damage.

Will a dirty air filter cause furnace not to work?
