Professional Awesome High Downforce Splitter Diffusers:

  • Designed and optimized using CFD to ensure the best possible performance.
  • Once installed, diffusers create a low-pressure transition zone that greatly increase the downforce potential of any splitter.
  • Designed to be installed on an otherwise flat splitter, instantly turning it into a high-end, active front element for a fraction of the price.
  • Use in conjunction with our universal vents to maximize downforce gains.
  • Engineered and manufactured in the U.S.A.
  • Made from high quality, durable ABS plastic.
  • 2 diffusers, left and right, included per purchase.
  • Diffusers are 2.25″ tall on the short side and 4.5″ for the tall side.
  • Used on the record-breaking Professional Awesome Time Attack Evo.

Install tips: Ensure adequate room in front of and behind diffusers to ensure airflow isn’t constricted for maximum performance. Designed to be riveted, bolted, and/or bonded to a splitter. Please ensure your splitter is properly attached to the car. These can, and will, create much more downforce and can rip the splitter from its mounts. YOU’VE BEEN WARNED!

    These diffusers are HUGE! Very easy to install and since they are cfd designed I know they make a bunch of downforce. The information that Professional Awesome provides makes it very easy to balance the aero on any car
