This Bell Mouth is designed to increase the volumetric efficiency of an engine by allowing for more air to be sucked in whilst being able to act as a resonating pipe that adjusts the pressure pulses inside the intake plenum. In simpler terms, Velocity stacks help for smoother airflow, which makes more HORSEPOWER!!
