    Does the job, economical and a perfect fit
    Size: 1" x 1" x 1"
    Bought exactly 1 year ago for 3rd Gen Tundra. So far, it really does the job. At first I didn’t realize how awesome it was until I had to remove and clean it yesterday. Although I keep my truck immaculate inside and out, after 1 years use, the filter had become extremely filthy and the air had an old mildew, vomit, stank smell. When clean and set for fresh air, I can only faintly notice diesel exhaust smells from those in front of me. I also notice little to no dust accumulation on my dash and flat surfaces. In my opinion the K&N cabin filter kit is an essential tool for cleaning this filter. K&N made the filter, so I would imagine that they know how to clean and refresh it properly. By the way, refresh solution is nearly fragrance free. I bought the refresh kit at a big box auto supply and it came in a mostly black box instead of the white box as sold on here. Don’t know if that means the formulation has changed or not.

    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.
