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.

Perfect Fit & Performance for 2022 Explorer ✅
Size: CA10242&CF12772, Size: CA10242&CF12772
I recently installed this filter set on my 2022 Ford Explorer (2.3L), and I’m very impressed with the results. Both the engine and cabin filters were a perfect fit with no installation issues. Performance & Quality: Solid Build: These feel much sturdier and higher quality than the filters I removed. I bought my vehicle used, and it seems the previous owners used whatever generic parts they could find. These are a noticeable step up. Fuel Efficiency: Since the swap, my MPG has remained rock steady at 26.1 MPG while running 89 octane fuel. It’s good to know the engine is breathing efficiently. Cabin Comfort: The cabin air is noticeably fresh, and the airflow is excellent—no whistling or restricted feel through the vents. Value: Getting both filters in one set is a great deal compared to buying them individually at a local auto parts store or the dealership. I’ll definitely be looking at these again in the next 6 to 12 months for my next maintenance cycle. Bottom Line: If you’re looking for a reliable, cost-effective alternative to dealership prices that doesn't compromise on performance, this is a great choice. See Old vs New Photo
