GARBAGE. Don’t waste your money
Absolute trash. The low pressure o-ring (orange) broke and split and broke in half after less than two hours of installation. Don’t waste your time and money on these cheap Chinese o-rings. The OEM Honda o-rings are literally cheaper and light years ahead of these in quality

Very satisfied with this air filter! It fits perfectly and was easy to install without any hassle. The filtration performance is impressive—helping to keep the air inside the car fresh and clean. The simple packaging is eco-friendly, which I appreciate. Reliable quality and reasonable price make this a great choice for regular replacement. Highly recommended!

Perfect replacements 👍🏼

Perfect fit at an affordable price. Engine air filter is good quality, but the cabin air filter is way better than the stock one. They even include instructions.

Worth every penny!
Size: CF11182&CA12051
I have a 2020 Honda Civic Sport, and these filters fit perfectly. I was hesitant in purchasing because it said that its a frequent returned due to compability. Installation was a breeze after watching a quick YouTube tutorial, although it does come with instructions/manual. They look solid and durable. They came individually wrapped. I’m hoping they help with the odor and fogging issues caused by the old filters.
Honda service wanted to charge me $63 for the cabin filter alone, so this was definitely a much better deal. I would purchase again in the future.
The item ID that I purchase is CF11182&CA12051.
