Seems that a lot of people struggle to find a suitable place for the large airfilterbox after fitting a 200 TDI (I know I did )
Here's what I did:
I combined both airfilterboxes into one, by using the 2,5 NA filterhousing and the 200 TDI box-lid.
You have to fiddle a bit with the internal tread to get the lid to screw on properly, but in the end you get a box that's much smaller/lower than the original 200 TDi box:
Next I used a bit of rainpipe to extend the intake-side of the box:
By sticking on the plastic tube that came with the TDI filter you get a nice and complete filterbox almost ready to go in:
The plastic tube-thingy connects to the old (TDI) filter pipe, no need to buy something new:
Here's the filterbox in place:
And the final result is a filterbox that sits nicely in the engine bay, low enough to let the bonnet close the way it should.
I secured the filterbox with a metal strip to the front wing and inner wingpanel.
