The air filter plays a vital role in engine performance by trapping dust, dirt, and debris before they enter the combustion chamber. A clogged or dirty filter restricts airflow, reducing fuel efficiency and engine power. Most manufacturers recommend inspection every 12,000 to 15,000 miles and replacement every 15,000 to 30,000 miles, depending on driving conditions. Replacing the air filter is a quick, low-cost task that improves acceleration and fuel economy. It also helps reduce emissions by promoting cleaner combustion. Always use a filter that matches your vehicle’s specifications. Keeping the air filter clean is one of the simplest ways to extend engine life and maintain optimal performance with minimal effort.
