The Nissan Xterra is equipped with two cab microfilters. The microfilters help clean the air inside your vehicle. Nissan recommends changing both filters at least once every 25,000 miles. The filters are relatively easy to access; changing them only takes a few minutes.
Visit your local Nissan dealer and buy two replacement microfilters. The part number is 999M1-VP051. You can also check your local auto parts store to determine if an aftermarket equivalent is available.
