I was wondering if any of you have installed the Nissan Filters for the A/C unit? Any feedback on its effectivity? I just did mine and it took about 15 minutes total time! The directions for mine were for the Frontier? The A/C unit is the same behind the glove box, but the glove box door and panel comes off with six screws. I know we suck a lot of dust up here on the trail in the summertime!!! So maybe this will help aleviate the problem. Maybe it'll keep me from doing the "Sneeze, Honk!" I'll replace it this fall when we are done wheeling for the year and see how dirty it got!!!
