Overview

These diffusers create a low-pressure transition zone when installed on an existing splitter. They are engineered and manufactured in the U.S.A. from durable ABS plastic and measure 12" long, 6" wide, and 2.5" tall with a 1" flange.

Show original supplier description

The Professional Awesome Splitter Diffusers are a pair of aerodynamic enhancements engineered using CFD to optimize performance and increase the downforce potential of any front splitter. By creating a low-pressure transition zone, these diffusers transform a standard flat splitter into a high-end, active front element. Each diffuser measures 12" long, 6" wide, and 2.5" tall, featuring a 1" flange for attachment. The package includes two diffusers. Installation requires ensuring adequate airflow around the diffusers. It is critical that the splitter itself is securely attached to the vehicle, as these diffusers can significantly increase downforce and potentially detach the splitter if not properly mounted.
