The DFR Diffuser mounts below the rear valence of the 2002+ or DF Rear Valence only. The diffuser is designed with four equal length fins that helps channel air flow as it exits from underneath the car. The diffuser extends to the bottom of the rear sway bars. This simple modification can be added without lifting the car (if the NSX is not lowered).
NOTE: This diffuser will not work with other aftermarket rear valence / bumpers. This diffuser will also not work with GEN1 rear valences (OEM 1991-2001).
