If its the 190bhp then it will be an S but this is more of a code name and all are K03, your will be the latest Ko3's for the B6.
Ah I know why it will not fit.
The 190bhp A4 comes with duel SMIC and the normal 1.8T's only come with Single SMIC and the TIP will not point or be the right shape to hook on to the Duel SMIC.
