Great quality and performance
Size: 1" x 1" x 1"
The quality of the filter is great and it is easy to installed in your car. Also, it helps to improve the performance of your vehicle, keep clean air flowing and avoid bad smells. What I love about it it’s the option to washed it and reuse it over an over.

Awesome product!
Size: 1" x 1" x 1"
Awesome product! Fit just as it should. A lot better then buying the replacement ones every time I do an oil change. I drive a mile of gravel roads everyday and this helps keep the dust from coming into the vehicle.

Fit my Subaru Forester perfectly!
This fit my 2024 Subaru Forester perfectly. The filters exhibited a high quality construction and was packaged well. Installation was easy and saved me a lot of $ vs. having my dealer install an OEM filter.
