No one really addressed my main original point / question. If all it takes to be considered a CAI is directing outside air to an air filter/air box in the engine bay, then aren't most / all OEM intake systems CAIs?
Anyone have an OEM / stock "HAI" example?
For the most part nearly all modern intakes can be considered "cold air intakes", 20 years ago it was far less common and the air-box had little if any access to the cold-air from the outside
the engine bay.
There are a few reasons why the change may have occurred but I'd put my money on the fact that it was an easy way to increase power
while allowing for better MPG.
The advancements and control manufactures are granted by modern ECU's allow manufactures them to hit their Fuel economy targets without having to physically
restrict the cars intake/exhaust like they used to in the 90's.
Let me throw in a monkey wrench on this one - would that CAI still be considered a CAI if you're driving in Arizona or Nevada during summer? How much lower should the intake temp be vs when placed in the engine bay to be considered as CAI? What then is the true definition of CAI that most of us can agree on? Or CAI is just a mindset? :-)
Well the engine bay is also going to be hotter in relation to the ambient temperatures outside the car, so in relative terms yes it would still be working as a cold-air intake.
Besides unless there is some type of phase changing or extreme cooling solution an air-cooled system cannot hit temperatures lower than Ambient.
