Hey got a new cabin filter to replace since my mom probably never did it… and as expected it was all black and crudy. I also went with a charcoal activated one from FRAM.
Now the issue is, well, I’m not sure really let me explain.
The airflow arrow on the filter should be pointed down since that’s how it goes. But the problem is have to notch the sides of the filter onto the notch that run on each side of the filter tray (picture for reference). Installing it with the arrow flowing down doesn’t fit in those notches because the filter pleates are to fat (picture). But installing it the other way around (arrow going up) it fits perfectly because the side pleates on that side are made to fit (picture)
So I’m at a dead end and not quite sure. Any inputs on this? Car is 2006 Hyundai Tucson by the way.
