Not all model Frontiers come with cabin air filters. If they don't come with filters, it is as easy as removing the 6 screws for the glove box, and cutting the two little strips of plastic out with a razor knife as shown above. Top filter goes in first, then the lower filter slides in.

The instructions that come with the package are easy to follow.

The complete list of items used in this project, and other projects, can be found in the Parts List below.
