The 2011 Nissan Altima uses a standard spin-on oil filter, and the exact part number depends on which engine you have. The car came with either a 2.5-liter QR25DE engine or a 3.5-liter VQ35DE engine, and both use a spin-on canister filter, not a cartridge. To be sure you get the correct filter, verify your engine type or VIN and cross-check with Nissan’s official parts catalog.
Engine options in the 2011 Altima
In 2011, the Altima was offered with two engines. The 2.5-liter four-cylinder QR25DE and the 3.5-liter VQ35DE share the same general filter maintenance approach, but part numbers can differ between engines. Always confirm the exact number for your specific vehicle.
2.5L QR25DE
The 2.5L QR25DE uses a spin-on oil filter mounted to the engine block. When replacing, remove the old filter, prepare the mounting surface, apply a light coat of oil to the new gasket, and thread the filter on by hand until snug, then follow the manufacturer’s torque guidelines.
3.5L VQ35DE
The 3.5L VQ35DE also uses a spin-on oil filter. The replacement process is the same as for the 2.5L: remove the old filter, clean the sealing surface, lubricate the new gasket, and install by hand until snug, then complete with the specified torque. To ensure you pick the correct part number, verify via VIN or owner’s manual.
How to identify the exact filter part number for your Altima
Because part numbers differ by engine and production date, use these steps to confirm the correct filter for your vehicle.
- Check the engine code label under the hood or on the VIN plate to determine if you have the QR25DE (2.5L) or VQ35DE (3.5L).
- Consult the owner's manual or the Nissan official parts catalog with your VIN for the exact part number.
- Inspect the existing filter for any numbers or cross-reference information that can be used to identify the proper replacement.
- Ask a parts counter at a dealership or reputable auto parts store with your VIN for the precise match, whether OEM or a compatible aftermarket substitute.
Using the correct filter ensures a proper seal and effective filtration. If you’re unsure, sticking with the OEM part or a well-rated aftermarket filter designed for the QR25DE or VQ35DE engines is a safe choice.
Summary
The 2011 Nissan Altima uses a spin-on oil filter for both the QR25DE 2.5L and the VQ35DE 3.5L engines. To obtain the right filter, identify your engine type or VIN and verify the exact part number in Nissan’s official catalogs or through a trusted parts professional. Regular oil and filter changes are essential for long-term engine health.
