John Henderson, Anderson, South Carolina
I replaced my OEM filters with the K&N cabin air filters and I noticed immediately a great improvement with my A/C getting much colder, much faster.
Kevin Johnson, Bluffton, South Carolina
Impressed with the sturdiness of thse filters. Tired of paying inflated prices for paper filters.
Thomas Kamsul, Lexington, South Carolina
The cabin air filter took a little bit of maneuvering to fit inside. I can actually smell the difference when I turn the A/C on. I'm glad that it lasts for the lifetime of my truck.

Perfect fit and after a month of usage I can tell the difference in the quality of air in the cab. Buy the best. You will feel the difference.
