There's an opportunity and an addressable market if you happened to be interested in offering a "fix" for this as a product.Check out post #71 in this thread where I detail some of it. There are a lot of gaps and inefficiencies in the OEM set up. The main killer is the absolutely huge gap between the side of the radiator and the CFRFP support panel, it's around 20mm either side, which if left uncovered is simply allowing large volume of airflow to do nothing but increase under hood pressures further reducing air volume going through the heat exchangers.
