2023 Honda CRV Hybrid - cabin filter was a bit long
Size: CRV 2023-26 2.0L Hybird
I have a 2023 Honda CRV Hybrid and the Cabin filter was a bit long. I had to trim the edges a bit to allow the cover to fit back on. The engine filter fit perfect.

Perfect
Size: CRV 2023-26 2.0L Hybird
After having my car for almost a year and searching forever to find an air filter this one fits I've had trouble at AutoZone and O'Reilly's with them saying different conflicting things as well as the dealership but rest assured if you have the 2025 hybrid this will 100% fit it's a great value for the money the quality is the same as you would get at the dealership

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself. I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price! Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway. The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit. If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended! Would buy again without hesitation.
