The Infiniti Q50 uses different oil filters depending on the engine under the hood. In practice, the vehicle relies on a cartridge-style oil filter, but the exact OEM part number varies by engine and model year. Confirm the correct filter by checking your VIN or the owner's manual.
Engine options and filter types
To identify the right filter, it helps to know which engine powers your Q50. The two most common configurations are the 3.7-liter V6 and the 3.0-liter twin-turbo V6. Each uses a cartridge-style filter, but the official part number depends on the specific engine and year.
- 3.7-liter V6 (VK37DE) — used on early Q50s and G37-derived variants
- 3.0-liter twin-turbo V6 (VR30DDTT) — used on newer Q50 models and updates
The exact filter part number should be verified in official catalogs or via VIN-based lookup, as Infiniti/Nissan update part numbers with new production runs.
3.7-liter VK37DE
The VK37DE engine typically uses a cartridge-type oil filter designed for the VK37 family. When ordering, rely on the exact OEM part number listed in Infiniti/Nissan parts catalogs or the vehicle’s VIN-specific parts diagram. Replacement intervals follow the manufacturer’s oil-change schedule, commonly around every 5,000–7,500 miles for synthetic oil, but always consult your manual for the precise interval.
3.0-liter VR30DDTT
The VR30DDTT engine also uses a cartridge-type oil filter, with the exact part number tied to year and market. Use the VIN-based lookup to confirm the correct filter and ensure compatibility with the recommended oil grade (often 5W-30 or 5W-40 depending on climate and model year).
How to find the exact oil filter part number for your Q50
To determine the precise OEM filter for your vehicle, follow these steps:
- Identify your engine code (VK37DE or VR30DDTT) and the model year of your Q50. The engine code is usually printed on the engine block or found in the vehicle’s documentation.
- Use your VIN to look up parts in an official Infiniti/Nissan parts catalog or a reputable online retailer (for example, InfinitiParts, NissanPartsDeal, or your local dealer’s parts system).
- Cross-check the filter type (cartridge) and confirm the exact filter part number before purchasing. If in doubt, contact the dealer with your VIN for confirmation.
- Consider using a high-quality OEM-equivalent filter from a trusted brand that specifies compatibility with your engine and oil specification. Ensure the seal and filter housing fit your setup.
By following these steps, you’ll identify the correct oil filter for your Q50 and avoid fitment issues.
Summary
The Infiniti Q50 does not have a single universal oil filter. The correct filter depends on the engine: the 3.7L VK37DE and the 3.0L VR30DDTT each use a cartridge-type filter with engine- and year-specific part numbers. Always verify the exact OEM filter using your VIN and official parts diagrams or consult your dealer to ensure a proper match. Replacing the filter along with the oil and using a quality filter helps maintain engine performance and longevity.
