The engine air filter is in a black rectangular housing on the passenger side of the engine bay; the cabin air filter is a separate filter located behind the glove box. These two components cover the vehicle’s air intake system, with the engine air filter protecting the engine and the cabin filter cleaning incoming air for the cabin HVAC system.
In the 2014 Frontier, commonly equipped with a 4.0L V6, the engine air filter housing is mounted on the side of the engine bay near the fender. Access is gained by releasing clips or screws on the housing. The cabin filter is accessed by opening the glove box and removing a panel, then replacing a rectangular filter. Always refer to the owner's manual for the exact steps and interval for replacement.
Engine air filter location
To locate and access the engine air filter, the following steps provide a straightforward guide.
- Park on a level surface and engage the parking brake. Turn off the engine and open the hood.
- Look at the passenger side of the engine bay for a black rectangular plastic box with an air intake tube connected to it.
- Release the clips or remove the screws that hold the cover in place using the appropriate tool (hands are often enough for the clips).
- Lift the cover and remove the old engine air filter, noting its orientation (air flow is usually marked with an arrow on the filter).
- Inspect the inside of the housing for debris; wipe clean if necessary and check the rubber seal for wear.
- Insert a new filter with the correct orientation, reseat the cover, and resecure the clips or screws securely.
- Reattach the intake tube and close the hood. Start the engine to ensure proper idle and no unsealed gaps in the housing.
In short, ensure the filter is seated correctly with the airflow arrow pointing toward the engine. A clogged or poorly seated filter can reduce performance and fuel economy, so replace it at the recommended interval.
Cabin air filter location
Separately from the engine air intake, the cabin air filter cleans air entering the passenger cabin through the HVAC system. In the 2014 Frontier, it is typically located behind the glove box.
- With the glove box open, locate the stops on the sides or remove a small panel that provides access to the filter slot.
- Remove the old cabin air filter by sliding it out carefully.
- Insert a new filter with the correct orientation (arrow indicating airflow typically pointing inward toward the blower).
- Reinstall the glove box panel or reattach the stops, ensuring the cabin is sealed when reassembled.
Replacing the cabin filter helps with odor reduction and HVAC efficiency. Check the owner's manual for the exact replacement interval, commonly every 15,000–25,000 miles depending on conditions.
Summary
For a 2014 Nissan Frontier, the engine air filter sits in a rectangular housing on the passenger side of the engine bay, while the cabin filter sits behind the glove box. Replacing either filter is a simple, tool-light task that can improve performance and air quality. Always consult the owner's manual for model-specific steps and maintenance intervals.
