One thing to remember about hood scoops/cowl induction. There is a high pressure zone right in front of the windshield that is why cowl induction works. Im not sure how big it is with the NX but stuff like my classic or my friends 79 mercury zephyr its pretty big. Sometimes the cowl works better than "ram air." Get you a large block of styrofoam and make your own scoop. Then lay fiberglass or carbon fiber, which ever you can get for a good price, and then you have a shape exactly like you want custom fit and would be a one of a kind.
