It reduces spiky vacuum occurrences during movement of the throttle butterfly valve, as the total intake diameter is approx 20% larger than that of the Throttle Body. I drive mostly urban which means lot of movements of the throttle. I used the flexible washing machine drain hose that costs approx USD 4.00 . I have changed that now to some plastic drain pipe and air conditioning insulation for a total of USD 3.00 and gets a smoother flow compare to the ribs on the hose.
