Tried looking at photos on site but hard to tell. Thanks !

Yes.
the driver side, is an intake to the air filter.
the passenger side, is an outlet. behind it, there is an electric fan, that will blow air out, when the temperature at engine compartment gets to a certain value (can't remember the value at the moment).
