The Audi S3 8V Flow-Lock Rear Diffuser makes extensive use of our Flow-Lock technology- a design system that utilises precision engineering and cutting techniques to create an integral mechanical bond. What this means for you is a durable, stylish and integrated rear setup with no visible fasteners. The perfect view for everyone behind you.

Our S3 8V Flow-Lock Diffuser paired with rear spats and winglets work together to complete the enhanced aggression our splitter kits bring to your S3 8V Sedan. Our rear diffuser and spat kits can be fitted without removing the rear bumper from your vehicle.

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.

  • S3 8V Sedan PFL Flow-Lock Rear Diffuser
  • 2 Flow Designs Stickers
  • Fitting kit with black stainless hardware

Material & Finish:

  • 10mm thick polyethylene composite rear valance with bevelled edges
