Lame old KKK K03 or K04 prolly.

Only because in this pic:

You will see it has 4 studs not 3.

And the k03 was too small on the 1.8T so I can't imagine them using it on the 2.0T.

change :o)

And I linked to the rest of the photos that weren't on the S4 post

It actually seems to be as loud or louder than my chipped 2000 A4 1.8T was.

And the boost dump is LOUD. Could never hear it in my old car. In this car it's as loud as my friend's 1.8T GTI with an aftermarket intake.

does this turbo have a blow off valve by any chance? im fairly new to audi itself and my car and when i drive, idk whether i should here the "pshhh" sound...
