The air filter and intake channels

Let in air of the engine contains parts of a dust which should not get to combustion chambers because they operate on walls of cylinders as a sandpaper. It would cause premature deterioration of pistons and internal walls of cylinders. Thus, the air filter provides necessary protection of the engine. Simultaneously it muffles admission sounds.
