Why is it important to keep induction air filters clean and replace them as recommended by the manufacturer?

• A. Clogged air filters can restrict the air entering the engine.
• B. They remove moisture from the intake air.
• C. Clogged air filters improve engine performance.
• D. Induction air filters have no effect on engine operation.

Answer: (A)

The main idea is that how well the engine breathes through the air filter determines how much air can reach the cylinders. The induction air filter is there to let as much clean air as possible flow into the engine while trapping dust and debris. When the filter gets clogged, it creates a restriction in the intake path, so less air can enter the cylinders. With less air available, the engine can’t reach its designed air-fuel mixture under load, leading to reduced power, slower throttle response, and poorer fuel economy. Replacing the filter as the manufacturer recommends keeps the airflow path clear and protects the engine from abrasive particles that could cause wear. The other statements aren’t true because the filter does not remove moisture, clogged filters do not improve performance, and the filter does affect engine operation.
