The 2014 Nissan Altima uses a standard spin-on oil filter with M20x1.5 thread; filter body size varies by brand but is generally around 65–75 mm tall and 68–75 mm in diameter.
Engine options and filter implications
In 2014 the Altima offered two engines: a 2.5-liter inline-four (QR25DE) and a 3.5-liter V6 (VQ35DE). For both engines, the connection is a spin-on filter with the common Nissan thread of M20x1.5, though the exact part number and housing design can differ between the two engines and among aftermarket brands.
Why the exact size matters
Filtration performance and a proper seal depend on matching the thread size, gasket fit, and overall canister dimensions. If you mix in a filter that isn’t compatible, you risk leaks or improper filtration. When in doubt, compare the replacement with your current filter or verify via your VIN-based parts lookup.
To verify the right filter for your Altima, follow these steps:
- Inspect your current filter for brand and model number, or take a photo before removal.
- Refer to the owner’s manual or service manual for the recommended filter specification for your engine.
- Identify your engine code (QR25DE or VQ35DE) under the hood or via your vehicle’s VIN, then cross-reference with a parts retailer for the correct filter that matches M20x1.5 threads.
- When purchasing aftermarket, ensure the product notes specify compatibility with 2013–2015 Nissan Altima 2.5L or 3.5L engines.
In short, the combined guidance helps you avoid mismatches and ensures a proper seal.
Options to source a compatible filter
Many buyers choose either OEM Nissan filters or reputable aftermarket brands. Use the guidance below to ensure you pick a filter that fits your 2014 Altima’s engine configuration.
- OEM/Nissan-branded filters labeled as compatible with the 2014 Altima’s engine (2.5L QR25DE or 3.5L VQ35DE). Check the exact part number against your VIN or the old filter.
- Aftermarket filters that specify compatibility with the 2013–2015 Nissan Altima 2.5L or 3.5L engines and explicitly note M20x1.5 threading.
- Ask a parts counter or dealer to confirm compatibility using your VIN and engine code before purchase.
Bear in mind that cross-checking with a retailer or dealer will confirm the right filter for your vehicle.
Summary
For a 2014 Nissan Altima, the essential size is the M20x1.5 thread. The engine choice (2.5L QR25DE or 3.5L VQ35DE) does not change the thread size, but it can affect the exact part number and filter design. Always verify using the old filter, your VIN, or a dealer parts lookup, and choose an OEM or reputable aftermarket filter that lists compatibility with the Altima and your engine type.
