It does work and very well all you have to do is figure out a way of getting cold air from the front of your car into the carby.

You will find all you need at the hardware store, all cars are different so there are plans that suit every car.

You might want to cut out an area behind the grille next to the radiator and set up some funnel style arrangement.

Try and get a good seal around the joints,and just use your imagination to work out how best to do it.
