Air Scoop - Why?
As not having driven/owned a car with a turbo, I've a non turbo impreza, what makes the WRX & the STI's a special breeed that they need an air scoop compared to other makes that have turbos, such as the modern day Ford ST's, or elderly Renault 5 turbos & the like?

I know the Impreza's have a top mounted intercooler, but do other makes have intercoolers, or are they set up in such a way that there is no need for them? Or are they at the front of the engine behind the grill & have no need for a seperate intake?

Most cars have small intercoolers mounted beside the front bumpers, due to the engine layout this works well. I understood they was fitted onto for subarus so they didnt get damaged on the rally? So people wanted the road cars to be similar? Also means the pipe work from turbo to inlet is as short as possible?

or its due to the design of the boxer engine rather than stuff you "heard" the scoop was there long before the rally cars existed.

I heard that scoops were fitted along with stickers to make the Impreza more desirable to the Chavs. BLow off valves however were considered overstepping the mark on a standard car.

Seriously, for a top mount a big scoop is the only way to get enough cold air in to it & two big vents let hot air out to help cooling further. Of course we all know the design is floored & at speed little air gets to the TMIC so most go for a FMIC which is far superior.
but sadly no scoop

Thanks for the replies to my question folks.
Perhaps should have worded my original post in such a way as to avoid looking like a total noobie, but as said, not owned/driven anything with a turbo fitted.
Should have worded it as uniqness of Imprezas having air scoop for the tmic compared to other performance cars with turbos that don't have such air scoops for cooling intercoolers.

I kind of agree with this statement , but would it really have cost more to have a FMIC as standard?
