What is a potential consequence of not servicing the air filter regularly?

Answer: A — Increased engine temperature

Not servicing the air filter regularly can lead to increased engine temperature. The air filter's primary function is to prevent dirt and debris from entering the engine’s intake system, ensuring that the engine receives clean air for combustion. When the air filter becomes clogged or dirty, it restricts airflow, causing the engine to work harder to draw in the necessary air. This increased effort can result in higher engine temperatures as the combustion process becomes less efficient. In addition, inadequate airflow can lead to a rich fuel mixture, where there's too much fuel compared to air. This inefficient combustion not only raises the engine temperature but can also result in poor performance and potential damage over time. Maintaining a clean air filter is essential for optimal engine cooling and performance.
