It's not exactly "ram air" or my original idea, but here's something that will make your hhr breathe a little better. thanks to the other people who made this modification to their stock airbox that gave me this idea!!
Basically all i did was cut a 3 inch hole in the opposite side of the air box from where the original intake was. i then purchased a 3" intake mount, and a 3" flexible air intake hose, bolted the intake mount onto the side of the air box, and tucked the hose between the radiator and the metal bar going across the top. throw in a few hose clamps and you've got yourself a second cold air intake supply!
I also plugged the hole in the air box where the intake pipe goes into the air box so as to block out any hot air coming into the engine.
