For an add Intercooler

[miche25]

Audi RS3 8V - 2018 - domwpipe & cool air CTS I plan to join Unitronic Stage 1 only.
They say with the purchase of a user intercooler ($700.) that I would obtain around 15-20 hp,
BUT what would be the other advantages?

intercooler?
well it keeps your temps down at a stable level for most of the drivability. if the temps are stable you'll get stable hp.
not sure what else were you thinking it would give you?

all these types of mods pretty much is for hp gains.
