Just wondering...I used to own a TT and over on their forums everyone raved about this:

Some Audi owner made it after starting with a CAI system.

Would something like this make a difference in a tC? Or would it only really help a car with a turbo in it since all TTs had turbos.

I really doubt that system significantly improves performance. There have been people slapping hoses on cars like that for years, and if it really did make a tremendous difference, a company like Audi would have picked up on it.

Incidentally, twin air intakes are just for looks. To my understanding, the more holes you poke in a vaccum system, the more pressure you loose...
