Ok so i repost, because i didnt really get an answer. But im missing the inner
plastic part that covers the SDMIC after i went into a ditch. Now i dont have one
and the SDMIC is some what exposed. Is it worh it to replace the plastic or should
i just leave it. Will rocks be problems mud etc? I know it should help the intercooler
because it will alow more air but whats the best thing to do??

 

ur missing the cover behind the SMIC rite or the plastic tge feeds in the SMIC, u have single SMIC rite, do u have a pick

 

Im missing the plastic shiedl just behind the SDMIC, infront of the wheel,
inside the wheel well, it basically stops mud rocks etc from going towards the
SDMIC, without it i can see the SDMIC with the wheel turned. I have 1 intercooler
and its a Fwd 2000 A4. Do i need the piece?

 

Throw a pic at us for clarification.

 

You are talking about the wheel well liner. It's about $50 from the dealer. You should get the S4 piece because it has vents to help airflow. Just explain to the dealer what you want.
