I presume the ITG modification was done at the factory,since it was their demonstrator.I had the wings of this summer,but I do not have a photo of the set-up.Though it is very easy.The plasric housing is removed and a conical ITG filter is insered in the plastic elbow that enters trough the bulkhead.The filter is fixed to the plastic elbow with the original clamp.The filters are for sale on ebay in many diameters.
I do not know if anything is done to the CPU, but I guess not.
