Mind 1 says great idea.. extra air feed that sucks in cold air -GREAT
Mind 2 says what a stupid place to put it... directly opposite the main feed so the air feeds will push air own each other creating air brrier stopping air going firectly into the intake...
I guess the pressure wont be great so MAY no cause a problem but something to consider.

Rich,
I don't think you'll find it's an issue.
Even at 100 MPH any positive pressure fed into the airbox is only a few inches of watergauge - next to ****** all - so 2 x next to ****** all wont cancel each other out.
Also, have you ever held you hand next to an exposed throttle body (or MAF or airflow meter) on full chat?
Quite a suction I can tell you.
So with an engine that's pulling a vacuum on the airbox volume, any supply restriction will show this up as a vacuum measured in the airbox...loads of air feeds only means you don't pull a vacuum - in effect you are supplying (or oversupplying) the needs of the engine.
The trick is to get enough air into the airbox at high enough air speeds to provide positive pressure in the airbox even with the engine on full chat...that would be ram air! It would be nice to have...but to get it you'd need to have a lot od space for ducting, do a lot of aurodynamic work to the bumper and finally test it in a wind tunnel.
Anyone have a wind tunnel at home? /ubbthreads/images/graemlins/wink.gif
