so based on this logic then the DCI should be useless, right? or what about all the scoops and ducts that are designed into high performance cars. are they only for looks and not function? just because bmw didn't design a more efficient air intake for their daily driven cars doesn't mean you can't improve on their design for higher performance. there's a good argument to be made for the blockage the scoops create over the radiator but imo at higher speeds it'll definitely force air into the tract. whether that is of any benefit is the question. common sense says it should but I am not a thermo dynamics engineer so I can't say definitively it does
