Your engine's air filter typically needs replacement every 15,000 to 30,000 miles, depending on driving conditions-more often if you drive in dusty environments. A clogged air filter reduces fuel efficiency and can impact engine performance. The Service team at Castle Chevrolet of Villa Park can inspect your filter and replace it with a genuine Chevrolet part if needed. We'll let you know if it's time, and you'll notice better airflow and efficiency right away. Stop by or call (630) 279-5200 to have your air filter checked.
