Great price. It does what it's supposed to do. Keeps my air flow clean. Super easy to install, I can't believe mechanics charge to do this. Once you see how easy it is, you'll save yourself that expense. The material is top-quality charcoal, so it cleans all the nasty mold particles from getting into the vehicle. There is no smell, and that is a plus.

Better then OEM

Size: (Pack of 1)

I’m writing this for my 2022 Honda Accord Sport 2.0T.. Honda wanted to charge me $85 to replace the air filter, immediately after I bought this filter for $17. Just changed it 5 minutes ago and let me tell you, it was identical to the oem Honda filter. Fit perfectly, quality was same if not better then the original one. Functions amazing and air quality is great. Car definitely felt happy after replacing it. 10/10

Routine Maintenance

Size: (Pack of 1)

This is my go-to replacement when I conduct maintenance on my personal vehicle. The item is amazingly easy to install (use YouTube tutorials if necessary). The quality and value for the money is better than what I can receive at my local service center. The option to order this every six months as Subscribe & Save is worth it!
