What's the point of an intake?
I mean, apparently you can't feel the little hp it makes and the sound isnt a huge difference. Wouldn't it be smarter to use those 3 bills to save up for an actual exhaust?

Its basically to match the sound for our car, the exhaust sound is from 0~3200 rpm, from the point on, you hear the intake sound, its just for sound purposes. Non of the performance mods are worth it if you are asking this question, for example.

For a tuner car the answer would obviously be for more hp, for our car, the answer is Sound,

I think he meant, the intake is part of the total airflow into and out of the engine.. So it would show more of an benefit with a more efficient exhaust, than with just a stock exhaust.

They are both components of the induction system, and decreasing the restrictions from either will benefit the overall volumetric efficiency of the air pump (the motor).

Only assuming there is a larger demand than the current configuration supports. The intake on the 2IS engines is large enough to support a whole lot more than 306 hp. Removing turbulence can only do a little bit when the velocity isn't all that high in the first place. Besides, if laminar flow were all it's cracked up to be, golf ***** wouldn't work. There's a whole lot more to effectively moving gas molecules from one place to another than making a smooth straight surface.
Also, restriction is a very relative term. Your powerband goal will tell you what is and is not a restriction. What's great for low end torque is very bad for high end torque and vice-versa.

Let's face it. There aren't a ton of bolt-on performance mods for the IS, so we take what we can get. The only reason I wanted an intake was for increased sound, because my car was too quiet. So, I simply cut a hole in my air box with my Dremel, and now I have sound when I want it. Under normal driving there is no difference and it didn't cost me a dime.
