What works best with the 2.0TDI and out of interest other engines?!
I’ve seen a lot of people running the Green Cotton Filter and other panel filters
But then again
I’ve also seen people running a Induction kit/BMC cold air intake adapted from the original intake pipe.
Looking at the intake box it looks like the air flows highly restricted with the shape of the pipe but obviously Audi spend a lot of money designing their cars so may give better results using their box with a high flow panel filter?
How has everyone else made the decision, any power figures floating around?
Any information would be greatly appreciated
