For 2006 and 2007, Subaru installed a rear air diffuser on the STI to help smooth out air-flow at the rear of the car. This kit allows this diffuser to be installed on any older STI, and all WRX’s, sedan or wagon. This diffuser has reduced cabin noise in our Project Car, and improves the look of the car from behind. The Kit includes: 1 - 1 – Cusco Bracket set 1 – Rear Diffuser 4 – Bolts for Diffuser The only part not included are two small bolts to attach the front bracket to the car. Please note that this kit is not compatible with the Whiteline Heavy-Duty Sway-Bar mounts, and will not fit if you have a tow hitch on your car.
