Got it when they couldn't
In stock and fast shipping was the selling point. My local auto parts stores didn't have this in stock anywhere. I got it in two days and cheaper than they could get it to me. Fits great and works like it should. I'm on top of my maintenance for all my vehicles, so it will get changed on time. Life span should not be an issue.

PERFECT FIT, EASY AF, HAPPY CUSTOMER
perfect fit for my 2022 civic! took 5 min! (not an exaggeration) soooo many youtube videos but alll you gotta do is -
1) locate engine air filter holder
2) undo fasteners on the sides
3) lift black part up
4) pull out old filter
5) put in new filter,
6) redo fasteners
DONE!
dealership wanted to charge me $85 for this!!!!! forget that , do it yourself! it’s easy for girls too!! don’t be intimated :)
