curious why people say the stock IC can only handle 12psi max...is it because 12+ psi it breaks or is it bc 12psi+ it can't cool the air enough?

 

I believe it's because it can't cool the air efficiently enough. That's the reason I've been told. But then again I'm sure that different people will have different reasons. Laterz.

 

The thing is pretty cute, huh?

 

the IC can only handle a certain amount. once this flow is reached the IC does not cool the air, thus increasing intake temps. hotter intake temps can lead to detonation, which is bad for your engine. not sure on the psi it can handle tho

 

I wouldn't even trust the stocker much past 10 lbs. If it was designed to handle that... Mazda would have installed a boost controller.

 

Not only does the stock IC not cool off the intake air very well, it has a relatively large pressure drop. This means your turbos are working harder to create the same manifold pressure than they would with a good IC like ASP/M2's.
