I know I am gonna say this in simple terms, and I also know some of you could come up with a nice formula to figure this out.

Where the Cold Air Intake goes into the box chamber in the front drivers side, is there enough air in there to feed it, or should I make a hole somewhere to allow more air in there ?

I know that the CAI sucks up X-CFM and that the area there can only provide Y-CFM. Is this enough ?

 

There are several paths for incoming air into that chamber. If you want more, build a scoop.

 

Yep, i have a scoop. Actually, the guy i got it from gained a 1 mph at the track with it

So its well worth it.

 

There should be plenty enough air down there. If you want more you could make a scoop on the bottom of the car. However, this may create a situation where after a few month you look under your car and there is a large amount of dirt on the inside of your bumper.
