There isn’t a single universal air filter number for a 2015 Nissan Altima. There are two filters to replace: an engine intake air filter and a cabin (HVAC) air filter. The exact Nissan part numbers depend on the engine (2.5L four-cylinder or 3.5L V6) and production date, so you’ll need to confirm via the VIN, the owner's manual, or a parts catalog.
This article breaks down where to find the correct part numbers and how to verify them for your specific Altima, so you can order the right filters with confidence.
Two air filters in the 2015 Altima
Most 2015 Altima models have two separate filters that may require replacement over time. The engine air filter and the cabin air filter each have their own part numbers, and those numbers can vary by engine type and production date. Below are guidelines to locate the exact numbers for your vehicle.
Engine air filter
To locate the engine air filter part number for your 2015 Altima, follow these steps:
- Identify your engine type (2.5L four-cylinder or 3.5L V6) from the door sticker, owner's manual, or VIN decoder.
- Check the official Nissan parts catalog or a reputable parts retailer by entering your exact model year and engine to pull the correct engine air filter PN.
- Inspect the current filter or the filter housing lid; some filters have the part number printed on the filter edge or housing.
- When in doubt, ask a dealership parts counter to verify the precise engine air filter number for your VIN.
By following these steps, you can be confident you have the correct engine air filter number for your Altima’s specific configuration.
Cabin air filter
To locate the cabin air filter part number for your 2015 Altima, use these practices:
- Check whether your Altima uses a standard rectangular cabin filter or a combined filter module by referencing the owner's manual.
- Look for the part number on the filter itself if you have the old filter out, or on the packaging when purchasing a replacement.
- Use your VIN to search Nissan’s official parts catalog or a trusted retailer’s catalog to pull the correct cabin air filter PN.
- Consult a dealership parts desk if you need exact confirmation for your VIN, especially if you have a premium trim or a cross-compatibility question.
These steps help ensure you acquire the correct cabin air filter number for your vehicle, avoiding fitment issues or improper filtration.
Summary
For a 2015 Nissan Altima, there are two distinct air filters to consider: the engine intake air filter and the cabin air filter. The precise part numbers depend on whether the car has a 2.5L four-cylinder or a 3.5L V6 engine and on production date. To obtain the exact numbers, verify your vehicle’s engine type and VIN, then consult Nissan’s official parts catalog or a trusted dealer/parts retailer. Replacing both filters at recommended intervals helps maintain engine performance and interior air quality.
