BOSCH 6070C HEPA Cabin Air Filter - Compatible with Select Nissan Frontier, Xterra

I was reading on nissan forums you can easily modify the air blower box (if you dont already have a cabin air filter on early frontiers/xterras) to install filters. These worked perfectly for that on my 1999 Nissan Frontier (look at the before and after pictures) The filters seal perfectly (I tested for air leaks around the filters with the blower on high and there was none) and with the included clip they stay secure. Only slight downside is i noticed a bit less airflow coming through the vents with the blower on but that was to be expected.
