Updated pictures with the funnel. The funnel helps so much. All it all easy and great mod.
When to a local auto store, bought the liter funnel. Pulled the vacuum hose out. Threaded the funnel on the hose and installed the hose back into the car.
Interesting. This is basically like turning your G airbox into a 350Z airbox. If I were to do it, I'd probably use a rectangular opening (2" X 3") and I'd block off flow to the over OEM over radiator intake. You don't really need three seperate air sources. Nice setup though.
