They will also let less and less air in, worsening car performance. If they do not get changed, they will eventually let more dust into the engine, shortening its life.

This is why your car manufacturer puts in an air filter on the air intake, so that as little dust as possible can make its way into the combustion chamber.Īir filters eventually get contaminated by dust, and need to be periodically changed, typically on a schedule specified by your car's manufacturer. Dust in the air could make their way into the combustion chamber and progressively degrade the metal surfaces and damage the seals, ultimately shortening the life of the engine very significantly. Your combustion engine burns fuel (gasoline, diesel, others) with oxygen (extracted from atmospheric air) in a sealed chamber to violently expand the mixture in it and provide motion to a shaft which ultimately drives the car wheels.
