There will be no bumper mods on this car...there is ample room for air to get to the cores through the existing ductwork. Long term additional brake ducting can be added, but this is a street car. The coolers have a shroud that can accept a duct which can truncate at the bumper. The brake ducts on the S4s are much smaller than on the S...it's really about the shape of the openings.

No need for fans...there is a lot of metal in these cores and by the time the car is making substantial heat loads, the car will be moving pretty hard.
