It's an old modification designed to save your Air Mass Meter. Many people over the years have had to buy new $200+ Air Mass Meters because the thermostat in their airbox failed, thus sending hot air to the engine ALL THE TIME. Easy solution - pull off the hose.

HOWEVER, some of us have recently started putting them back on. We've noticed that even a properly functioning thermostat will allow some small amount of hot air to flow, even when extremely hot; it would seem that the hot air valve isn't just a ON/OFF kind of thing, but rather that it is designed to provide a mixture of hot/cold air to keep the air entering the engine at a particular temperature. It's probably designed to provide warmer air for a cleaner burn and better mileage. With the cost of gas, a lot of us are ready to take a hit in performance in exchange for better mileage.
