OVERVIEW

Maximize the downforce of your front splitter with the Ansix Auto Diffuser Tunnels for the 2022+ BRZ/GR86. Designed for easy installation on any flat splitter material — including plywood, plastic, aluminum composite signboard, fiberglass, or carbon fiber — these tunnels create a pressure drop between the splitter and the road, delivering superior downforce compared to a flat splitter alone.

FEATURES

• Designed for use with any flat splitter material
• Made from durable 1/8" thick vacuum-formed ABS plastic
• Textured top surface, smooth underside
• Easy to trim for a custom fit
• Improves aerodynamic efficiency for increased front-end grip
• Recommended to pair with vented fenders for maximum performance
• Can be fastened with hardware and bonded for secure mounting
• Sold in pairs

• Surface Finish: Textured top, smooth bottom

SCIENCE

By creating a volume expansion (formed between the splitter and the road) the pressure drop occurs giving superior downforce compared to a flat splitter.
