    Flow Design Audi S3 8P PFL Sportback Flow-Lock Rear Diffuser

    Experience Flow-Lock rear diffuser for your S3 8P, sharing the same durability and technology as our renowned WRXGolf GTI and Focus RS line up - trusted by many car enthusiasts worldwide. The rear valance and diffuser fins will clear the S3 8P exhaust tip with ease, rear bumper removal is not necessary for installation of the diffuser.

    The Flow-Lock interlocking system allows for the final assembly of the diffuser fins without tools or fasteners. A simple push and click and the kit is assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your S3 8P rear.

    Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure). It is also possible to install when your car is on the ground.
