If you do not regularly exchange the air filter, what effects does this have on the engine?

If the air filter is not regularly replaced, it becomes clogged with dirt and particles. This restricts the airflow to the engine, leading to incomplete combustion. As a result, more harmful substances are produced in the exhaust gases, increasing pollution (point 1). The engine then needs to use more fuel to compensate for the reduced air supply, which raises fuel consumption (point 2). Additionally, because the engine cannot get enough clean air, its overall power output decreases, making it less efficient (point 3). Regular air filter maintenance ensures optimal engine performance, fuel efficiency, and reduced emissions.
