The 2017 Nissan Altima has two air filters: the engine air filter in the engine bay and the cabin air filter behind the glove box. Here’s a clear guide to locating both and replacing them.
In most Altima models from this year, routine filter checks help maintain engine performance and interior air quality. The cabin filter protects the HVAC system and occupants from pollen, dust, and odors, while the engine air filter keeps debris from entering the engine intake. Replacement intervals vary by driving conditions, but checking at least once a year is common practice; refer to the owner’s manual for the exact recommendations.
Cabin air filter: location and replacement
To replace the cabin air filter in a 2017 Altima, you’ll access the HVAC housing behind the glove box. Replacing this filter can improve airflow and reduce odors inside the cabin.
Follow these steps to access and replace the cabin air filter.
- Open the glove box and remove contents to clear space.
- Gently squeeze the sides of the glove box to release the stops and allow the box to drop down or pivot downward.
- Look for the rectangular cabin filter housing behind the glove box and release the cover by unclipping or unscrewing as needed.
- Remove the old filter and note the orientation of the filter so the new one can be installed correctly (arrows should indicate airflow toward the blower).
- Insert the new filter with the correct orientation, reseal the housing, and reattach the glove box.
- Push the glove box back into place and restore any items you removed.
With the new cabin filter in place, the HVAC system should feel more effective and odor-free. Check the filter area at least every 12,000–15,000 miles, or sooner in dusty conditions, and replace as needed.
Engine air filter: location and replacement
The engine air filter sits in a plastic airbox in the engine bay, typically on the passenger side near the front of the engine and connected to the intake tube. Replacing it helps maintain engine performance and fuel efficiency.
Follow these steps to replace the engine air filter.
- Open the hood and locate the engine air filter box, a black rectangular housing secured with clips or screws.
- Unclip or remove the screws to lift the lid and expose the filter.
- Take out the old filter and inspect the housing for debris or damage.
- Insert the new filter in the same orientation as the old one, ensuring the folded edge and seams align with the housing.
- Reattach the lid and secure the clips or screws. Close the hood when finished.
Replacing the engine air filter can improve throttle response and efficiency. Plan to replace it around 30,000 miles under normal conditions, or sooner in dusty or harsh environments, and always follow the vehicle’s specific maintenance schedule.
Summary
The 2017 Nissan Altima has two essential air filters: a cabin air filter behind the glove box and an engine air filter in the engine bay. Replacements are straightforward with basic hand tools, and correct filter orientation is important for optimal performance. Regular checks—typically every 12,000–15,000 miles for the cabin filter and around 30,000 miles for the engine filter (adjust for driving conditions and manual guidance)—keep both the interior environment clean and the engine running smoothly.
