I've always wondered, why not tap into the HVAC cowl vent instead? It would make a nice factory look with all the benifits of a cowl intake. Obviously I am missing something on why people don't do it. Not enough air flow?
I am pretty sure you could do this. There is already a drain for the cowl (obviously) so as long as you could get a 3" tube in there somewhere, should work!
I actually have my heater box out right now, I might take a look at it tonight.
