I heard the Eventuri units do provide a smoother overall flow & therefore offer a touch more consistent air volume. There was a detailed deeper dive video somewhere showing the dimples on the inner walls of the intake inlet tubing that resembled the texture of a golf ball. And the smoother air flow increased the speed rolling over it resulting in better / easier breath for the S58 in the tight engine bay. This is something I'm confident the DINAN system doesn't have. To measure the HP gains on each unit would take some super precise equipment though. I did like the lower front bumper center section in the body color. That looked nice.
