My friend is looking for a cold air intake for his 96' audi a4. I have looked around quite a bit, but i havent really found anything that looked too promising. Any help would be great becuase i am really unfamiliar with the Audi's

From what I've read around the web the Audi intakle system is not all that restrictive. You won't notice much of a gain, just a growl.

Correct best you can do is smooth out the internal air box.
