You will need to make some kind of ductwork.  I think there would be 
two things you should shoot for:  bringing in cool air from some 
place where the engine heat doesn't reach, and making sure the duct 
is large enough in diameter that it does not unnecessarily restrict 
the flow of air.  It might be good if the duct entrance faced forward 
so it would have some ramcharge effect at speed, but it is not clear 
that the benefits of this would exceed the downside of the longer 
ducts required.  You would also need to consider how to make the 
ducts survive in a rollover.
