WHat do you mean?
Literally, it's Air Filter> Filter housing>Air bridge/MAF>Throttle body>Plenum>runners>ports>Through the intake valves.
About like any port injected engine.

Mostly through the radiator, up past the engine and around/over the radiator shroud, into the air filter. Why C4, 5, and 6 "CAI's" aren't really cold (or ambient) air. There IS no managed "path" for the air to take from outside the car to the filter.

Breathless Performance has a CAI setup called the Vortex Ram Induction System that takes cold air from under the front end and flows thru a conical filter then thru the oval air tube to the TB. It requires cutting a hole in the upper shroud and attaching a box to it.
The down side to systems like these is that if you drive thru standing water, it's possible that water can be sucked up into the intake manifold. Not a good thing to happen.

If you look below the air filter you will see about a 1" gap between the upper radiator shroud and the back of the front bumper. It goes all the way across between the two frame rails. That gap is how the air gets from the area in front of the AC condenser to the air filter.

Dave MacLellan himself has stated that the majority of the air the engine gets on all C4s is air that has gone through the radiator and curves back around to the filter.
