I have been wondering why the Impreza needs a scoop to direct air into the intake?

I have run a number of cars which are significantly more powerful, bigger engined, higher revving and none of these have needed a scoop.

So why do Impreza's need one? Is the under bonnet design just inefficient or what?

because the intercooler is mounted on top of the engine!!

 

Cold air direct to the Intercooler, same reason why the other cars with scoops have them

 

They dont. The scoop is to direct air onto the intercooler.

 

^^^^^^^What he says!...

 

Why front scoop is for one reason and this is TMIC(Top Mount Intercooler).If you are running FMIC keep this for future like is Oil cooler.

 

Why did/do Subaru go with a TMIC though? FMIC is a better solution isn't it so why not change it over time?

TX.

 

Less lag due to the shorter pipework.

 

Cos they needed a reason to put a big scoop on the bonnet, would look pretty gay wiout a big hole int bonnet
