While I was crawling around the car yesterday I noticed this plastic piece under the passenger seat. It looks just like a dual tip exhaust pipe, but its the air duct. Pretty cool as its the first car I've had that has this. A bit more comfort for your rear seat persons.

 

Im pretty sure most newer cars have these.... a lot nicer for rear passengers

 

Yeah i noticed this recently too, i didn't think it would have them. Very nice feature.

 

Yup, I have em too, didnt know they where there, They where in my nissan SE-R too.

 

those things have been around for a while my 1991 Grand Prix had it and my 2001 Cavalier has it

 

If your ever wondering what that circular arrow icon in your defrost or vent controls meant, this is it.... these vents are used to bring out the fresh air
