My brother who is computer illiterate would like to add a side air scoop to help push more air into the radiator on his Dutch Star. I am requesting your input on 2 things and will happily relay the info to him: 1) Is this advisable to do? Are there any downsides to this approach 2) Do you know of any sources to obtain a side air scoop of this type? Appreciating y'all in advance.
