Most of the new cabin filters from mitsu are "activated charcoal" type. The absorb alot of the "funk" floating in the air. If your EVO didn't come with one, you may have to cut the blower housing to install it. Mitsu has a technical service bulletin about how to install. Here is the pic.

Mitsu says replace every 15,000 or more frequent in dusty/high pollen areas.
Its a small price to pay healthy breathing.

 

wow..........thats crazy.

guess ill be checking mine then.......LOL

 

What if I don't have a filter installed? What am I breathing in? Since I have a the 03 the box is shut out. I've been procrastinating doing the install since it wasn't done by the 1st owner.

 

at least there wasn't a rat in there

Yikes, I'm gonna check mine soon as well, what with all the yellow pollen crap floating around the area lately. Good thread.
