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.

Filter fit perfectly.
Size: 17220-5LA-A00
It fit, so that was my first concern in buying this as the price was low for a 2-pk. I bought it since it said good for 24,000 miles whereas another I was considering was only 12,000. I know I went more than twice that so will see how it holds up. Coming from a brand I never heard of, but what was available on Amazon.
