The engine air filter prevents dirt, dust, and debris from entering the engine. Over time, it can become clogged, reducing airflow and potentially affecting engine performance. Regular replacement helps maintain fuel efficiency and engine longevity.

The cabin air filter cleans the air that enters the interior of the vehicle through the heating, ventilation, and air conditioning (HVAC) system. It helps filter out dust, pollen, and other contaminants, providing clean air for the occupants. Replacement intervals vary, but it's generally recommended to change the cabin air filter every 12,000 to 15,000 miles.

The fuel filter ensures that clean fuel reaches the engine by trapping impurities and debris. A clogged fuel filter can lead to fuel delivery issues and affect engine performance. Replacement intervals vary, and it's often recommended as part of regular maintenance.

The oil filter removes contaminants from the engine oil, helping to keep the engine components clean and lubricated. During an oil change, it's common to replace the oil filter to ensure continued protection of the engine.

In vehicles with automatic transmissions, a transmission filter helps keep the transmission fluid clean. Over time, the filter can become clogged, affecting the transmission's efficiency. Transmission filter replacement is typically recommended at certain mileage intervals or during a transmission fluid change.

While not a traditional filter, the PCV valve helps control emissions and maintain proper pressure in the engine crankcase. It may require replacement during a tune-up.
