Good non OEM replacement filter
Size: 165465NA1C
I recently purchased the Forccord 2-Pack Engine Air Filter for my INFINITI QX50 (2025/2024-2019) and QX55 (2025/2024-2022), and overall, it’s a decent alternative to the OEM filter.
Pros:
Perfect Fit – Installed easily in my QX50 without any issues. Fits just like the factory filter.
Good Filtration – The material seems effective in trapping dust and debris, helping keep the engine clean.
Affordable 2-Pack – Great value compared to dealership prices, especially if you replace filters regularly.
Improves Airflow – Noticed a slight improvement in engine responsiveness and fuel efficiency.
Cons:
Not OEM Quality – The filter material feels a bit thinner and less sturdy compared to the original Infiniti filter.
May Not Last as Long – While it works fine now, I’m unsure if it will hold up for the same mileage as an OEM filter.
No Installation Instructions – Though easy to install, a simple guide would have been helpful for first-time users.
Final Thoughts
This Forccord air filter is a good budget-friendly replacement that fits well and performs decently. However, if you prioritize OEM durability and quality, you may want to stick with the original Infiniti filter.

Verify your engine size! 17220-5AA-A00 filter for 1.5 liter turbo. 2.0 uses different filter.
Size: 17220-5AA-A00
17220-5AA-A00 for the 1.5 turbo engine (we have a 2017 Civic EX-T), 2 pack of filters, use 1 at a time so 2 intervals, about 15k-30k miles per interval, it's about 30k-60k miles worth of air filter.
Works as it should, fits, compatible, nothing fancy, does its job.
For the turbo it's a few screws or nuts (use the socket, less chance of stripping, don't over tighten when you put the cover back on), front of engine compartment, you could do this while dressed in fancy clothing.
First mechanical thing that I had our son do, I gave him guidance, literally the first time he popped the hood. Took maybe 10 minutes, and that was him being careful and being new to using tools.
I'm not a professional but I work on our vehicles, have done a bit more than basic maintenance. This air filter replacement procedure is as straightforward as they get.
