Fergy, This is the reason I am attempting to make the airbox. I have been told, that the majority of the air that enters the ram tubes actually is drawn along the outside edge, and not from directly in front of the opening. If this is true, then placing "socks" on the Ram tubes should be detrimental to performance. This must have some validity, as I believe most (if not all) super tourers use an airbox, with exposed Ram tubes. On top of this, when the car is on the dyno it is tuned without the air filters, surely, placing the air filters on after setting the air/fuel ratio must also be detrimental - possibly cause the car to run a little richer by restricting the air flow?
I plan to build an airbox to enclose the trumpets, and then attach a Ram Pod (off my old WRX) to the front. this will allow me to place the filter in a position to maximise cold air intake also. I'll keep you up to date.
