Looks as good as the genuine one.

This looks like a quality product, great for the price. It looked identical to the genuine Honda part but was $20 cheaper than the Honda one.

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.
