Mein Auto: 11' Audi S4 Prestige
If by upgrade you mean you want more power take a look at burger tuning. most people run some sort of variation with a juicebox. I ran a JB+ on mine (easy to remove and install takes less then 5 minutes plug and play) and gives 40HP to the wheels at stock setting.

They have further tuning chips as well but i liked my JB+ i ran for about 3 years until i sold the car. I have a jB+ for sale currently for 200 shipped if your interested let me know. I just sold my 335i.

Do a quick search on JB+ on these forums youll see tons of 335i owners have some sort of juicebox on thier car.
