The NACA submerged duct is very efficient.
If you have a good mathematics and fabrication background you can make one yourself. (Despite what you see written, this report is unclassified):

Or you can do it the easy way and just buy one pre-made and simply blend it into the hood:

Here is an installation article, although I'm not sure how good it is because I am not a fabricator.

It's not very clear in that video, but it looks like a marine clam shell or cowl vent. Check your local marine supply shop.
