Intake question...

Alright, you know that little intake housing that sits right on top of the throttle body? What is that called? And would I be able to swap it with one from an si? Also, where could I get one?

that thing is known as an air chamber. what sits below it are 2 fuel injectors ( thus the name dual point injection.) you CANNOT swap one from an si because si's use multi point injection (four injectors as opposed to 2.)and do not have this, they have throttle bodies.

he can just needs the whole shabang from the SI then hes got like 20 horses extra. But otherwise you got it
