These systems utilize aluminum piping from the throttle body and drops their cone filter with velocity stack down in the fender/bumper of the vehicle. This separates the filter from the hot engine compartment. The result is your intake system drawing cold air away from the hot air present in the engine compartment. Horsepower gains can be seen by as much as 15 HP's! This is accomplished by gaining 1 HP for each 10°F reduced. Many applications apply.
