basickly you could make a hose going from the stock snorkle hole to the bumper to get freash air,the way i would do it is to remove the pasanger side fog light make a velocity stack and run a pipe up to the snorkle hole which is followed by the box which keeps the hot air out i would make the box that houses the filter element out of fiberglass since it doesent heat up like aluminum does ( race cars use it because there always moving air never standing still like a daily would) if you get aluiminum pipes wrap them in exshaust wrap to keep the pipes cooler
