If you look under the hood of a WRX, the intake path is a little convoluted. Air enters a large channel near the hood latch that funnels diagonally across the front of the engine compartment. It then drops down into the fenderwell, passes through a bulbous silencer and then returns via the main intake channel heading towards the manifold.
So, here's the question: is the silencer in the intake path too restrictive for the turbocharged engine?
You'll often see sites talking about a silencer delete procedure which will definitely make more noise. What's not at all clear is whether removing any of this piping has any effect on total airflow.
Note: I'm not asking about power, tuning or whether the sound is cool / less so. The question is whether removing the silencer components will remove a restriction and increase net airflow.
