Back in the day, my brother wanted to run some Homedepote plastic tubbing from the Sentra's AC vents then to the intake (yes you read that right: glue or screw plastic pipes over the ac vents and runthem to the air-intake). Basicaly he was thinking that not only would this give him boost, but would also be really cold air which would give him more power. I told him that he will lose power since the AC would drain more power then his contraption would make. He did not want to hear it, but thankfully he never went through with his idea.
