In theory, CAIs develop horsepower and torque gains by improving the engine's intake air flow. They are supposed to result in improved intake air flow than stock systems to achieve better engine efficiency and the lowest possible intake air temperatures.
Cold Air Intake is any intake which draws the cool air from outside the engine compartment. This term exists b/c for some cheaper cars the factory intake draws the warm air from the engine compartment. Our cars are very well engineered from the factory to draw cool air from the kidney grille area already. A more proper term to call those aftermarket intakes would be "high-flow intake".
Another dumbass.. Listen, I will do baby language.. THE FORUM IS MEANT TO BE USED TO ASK QUESTIONS. If eveybody knew answers to all quetions out there, this forum would not exist!!! Wow another forum "EXPERT". Do someting productive as stop breathing.
Hell if there are more people like you around, I will probably end up selling my E46.
Hey I'm all for the easy questions. These allow me to flaunt my obviously superior knowledge (everyone in unison -> )of all things powerful(and up my post count). You cant have a forum god complex if you are a forum god
Disclaimer: all the above was pure BS and should only be contrued as mindless drivel. Shouldn't matter since no one pays the poster any attention anyways
Better for the engine is kinda right. It is more efficient which allows you to push the engine harder and have it respond appropriately. If having a CAI makes you want to redline you car all the time it might not be 'better'(but it does make it a little more fun):thumbup:
