When the engine air filter is clogged, it restricts airflow into the engine, which reduces combustion efficiency. This can lead to reduced fuel economy, lower power output, and slower acceleration. Prius owners should inspect and replace the engine air filter every 12,000 to 15,000 miles o r more often in dusty environments.
