Hi, I have an 09 MKV GTI and the guy i bought it from put a K&N intake in it. i have the original intake and have replaced it, but still have a question:

Does just having the intake increase my car performance even though i haven't modified the the fuel/air ratio?

Just a bit. If you check your intake air mass(group 002) you'll see a slight increase.
However, with the maf sensor reporting more mass air, the ecu will increase the requested fuel resulting in the slight HP gain.
Will you notice any gain? Not likely due to it only being a slight increase.

The biggest gain is in the "THIS SOUNDS EFFING COOL!" section of your brain.
