A true CAI will draw air from outside of the engine compartment.
Not to say that people won't get a boost from an SRI, especially if it's less restrictive than OEM and fresh air is quickly moving through engine bay. That's why you'll see people dyno their intakes with the hood up and large fans blowing at the front of the car.
