The engine air filter for a 2017 Nissan Pathfinder is Nissan part number 16546-9G000. This OEM filter is designed for the 3.5-liter V6 engine used in that model year. If you’re unsure or your Pathfinder has a different setup, verify the number with your VIN or by checking the label on the air intake housing under the hood.
Context and scope
Understanding the correct air filter number helps ensure you buy a filter that fits properly and maintains your engine’s performance and fuel efficiency. While the 2017 Pathfinder shares a common engine platform, production changes and trims can influence the exact part cross-reference. The information below lays out how to confirm the right part and what to consider when replacing it.
Where to find and verify the correct engine air filter number
To help you locate and confirm the exact part number for your truck, follow these practical steps.
- Step 1: Open the hood and locate the engine air filter housing, typically on the passenger side near the front. The cover is usually secured with clips or screws.
- Step 2: Inspect the filter itself or the inside of the housing lid for a printed part number. The OEM number for many 2017 Pathfinders is 16546-9G000, but verify this on your specific vehicle.
- Step 3: If the label is missing or illegible, consult the owner's manual or contact a Nissan dealer with your Vehicle Identification Number (VIN) to confirm the exact part number for your trim and production date.
- Step 4: When purchasing, ensure the replacement matches the OEM size and seal; a filter that doesn’t seat properly can cause unmetered air intake and engine issues.
Verifying the correct part number using these steps helps you avoid ordering the wrong filter and ensures optimal filtration and engine protection.
OEM versus aftermarket: what to consider
When choosing between an OEM filter and aftermarket options, keep these considerations in mind to protect your engine and warranty.
- OEM reliability: Using the Nissan-approved engine air filter helps guarantee fit, filtration efficiency, and compatibility with the engine’s intake system.
- Compatibility and fit: Check that the aftermarket filter advertises compatibility with the 3.5L V6 Pathfinder and that it matches the same dimensions, seal type, and airflow characteristics as the OEM part.
- Quality and warranty: Select filters from reputable brands with clear warranty coverage; cheaper options may save money initially but could compromise filtration or fit over time.
In practice, many owners opt for OEM or reputable aftermarket replacements that explicitly list compatibility with the 2017 Pathfinder and the 3.5L engine to minimize risk of fit or performance issues.
Summary
For the 2017 Nissan Pathfinder, the engine air filter part number most commonly cited by Nissan is 16546-9G000. Always verify the exact part number for your specific vehicle using the VIN, the air-box label, or guidance from a Nissan dealer. When replacing, prioritize a filter that matches the OEM specifications and fits securely to maintain proper filtration and engine health. The choice between OEM and reputable aftermarket options should balance fit, price, and warranty considerations.
