on a stage 1, right from you turbo outlet the piping will go directly to the throttle body. stage 2 (intercooler upgrade) the out let of the turbo will shoot down directing the air through the intercooler then up to your throttle body. The intercooler will lower the tempature of the air. Colder is better
This is why you are limited to a certain boost non intercooled. b/c the air will get too hot and cause detonation.
