This plug inserts into the rubber/silicone Air intake hose when one decides to delete their blow off valve or set their blow off valve to non-circulating mode (Vent to atmosphere)
Without a plug in the intake pipe, the ECU would not run properly as it will miscalculate the amount of air entering the motor.
