I'm not the quickest when it comes to rule interpretation, but is anyone else reading this to say you can cut holes in your splitter to duct air to the RADIATOR?? The decision specifically mentions brake ducts and oil coolers, but what about an opening between the attachment points in the bumper cover and the "vertical plane" for radiator air?

Or is it saying ALL air must be ducted so that none of it spills over into the engine compartment?
