Great little bang for buck and DIY savings from the Dealership Service DEPT
Easy to install and very simple to place into the correct compartments in the glove box and engine bay. Took maybe 15 minutes or less. Quality is great and the air in the cabin is so fresh now! The quality of the air filters is OEM+ which is great when trying to save some money and add value to the product. Fits perfectly in my 2020 Honda civic Sedan. Includes everything needed to replace both filters. Includes both cabin and engine air filter

Fits 2017 Honda Civic
This fit perfect for my 2017 Honda Civic. It looks and feels super similar to the ones I removed so they seem of equal quality. As for value? Can't beat it!

Perfect fit for 2025 Honda CR-V Hybrid Sport
Size: 2023-26 CRV 2.0L Hybrid
This filter pack was a perfect fit when needing to replace the cabin and engine filter for my 2025 CR-V Hybrid. My Honda dealer wanted $140 ($70 ea.) to replace both filters while this pack only cost $30. The cabin filter was a piece of cake, but the engine filter took a bit of an effort. Nothing too crazy, though. Definitely worth the money.
