• One of the top aero mods for Mustangs

• Mounting holes and slots for perfectly centered easy install and adjustability

• CNC machine cut in the USA from high quality high-density polyethylene material

• High quality that's not a floppy poor design

This rear diffuser will definitely make you stand out from the rest with aggressive styling and quality above the other diffusers out there. Same design as our aluminum diffuser. Diffuser blades on stock diffuser are centered with the EMP diffuser blades for a clean professional look unlike the uncentered lopsided blades of our competitors diffusers. Easiest install of all the diffusers on the market with mounting holes (yes the competition has NO mounting holes so you just guess where to put the screws in), slotted attachment to two existing bolts to ensure center section is perfectly centered and adjustable to get the desired gap from rear of car. Comes with black stainless steel screws, nuts, bolts, brackets and stainless steel lock washers. Strong and remained steady during 155 MPH test - Lapped the Daytona 500 Race Track with one installed. Easy installation.

Specifically designed for 2015-17 Mustang GT, V6 and EcoBoost and 2018-22 Mustang GT, EcoBoost, and 2020+ EcoBoost High Performance Package with stock rear bumper. Will not fit Mach 1 or Shelby models.
