Default ram air

i am thinking of doing a hood scoop intake this thanksgiving simlly by adding another 90 degree elbow to the existing one on the air box so it draws air directly from above it (scoop) so i will make a new custom one from plastic. My only concern is if i cruise on highway and air is forcing itself in , the 2001 uses MAP is a air density senser, so if i get more air than natural,, what will be the side effects? good or bad?

The main drawback is rainwater, but ya, this has been done before in several itterations. Works well in most cases.

Having done this before, I can tell you you'll find all kinds of bugs, leaves, and crap in your filter -- so you will have to change it more than often.

Other than that, it sounds great, and performance-wise beats out any under-hood CAI.

Just watch out for water!

Edit: since someone will call me on it, I'll say right now that "no, I don't have hard numbers that back up my performance statement above"

Just slap on a cone filter to your throttle body. I think bugbomb or bug bomb has done this.



I would've done the same thing to my MY02 Impreza, but I don't have a hood scoop as stock and I wasn't about to go to SM class for a stinkin' hood.

FWIW, you'd need an oil catch can or something similar to connect the valve cover and pcv hoses to. But it would sound great..!

Right, right. I've never done it so I don't know how you would connect the hoses, but I've seen it done before so it's possible.
