Anyone got one of these fitted?

realised this might be opening a can of worms with peoples opinions but i have spotted that K&n do a fitted closed box induction kit that apparently fits the 2.0tdi engines

any actual gains from this?

few years ago I had a 2.5 petrol BMW and fitting a cone k&n was the best thing i ever did to that car so was curious on if the is any actual gain to fitting this to TDI engines/ A3 2.0tdi models

anyone got any experience of this kit?

thanks
