MP Performance Style Black Rear Bumper Diffuser For BMW 5-Series G30 Sedan 17-19. Note: Fit models with M Sport bumpers only. Does Not fit M550i or M5 models. The rear end of a car underbody is where a diffuser is usually located. It accelerates the velocity of the airflow underneath the car to create downforce. The pressure under the car is affected by the diffuser so that it can expand back to ambient in the diffuser, as the car moves forward, such that the pressure decreases while the velocity increases. Since the pressure below the car is lower than on the side and above the car, downforce is produced if implemented correctly. The diffuser “drives” the underbody, which produces the downforce.
