Product Description

Add a different look to the rear of your 2013-2014 Mustang with a Boss 302 rear valance/diffuser. This is the same Rear Diffuser/Valance that is factory equipment on the 2013 Mustang Boss 302 & California Special. It features a black textured finish & is an OEM Ford part. This rear lower valance/diffuser is an upgrade for 2013 Mustang GT and V6. Installation of this kit on your 2013 Mustang GT will require you to cut off the lower section of your bumper cover & cut new slits to retain the lower valance. Luckily Ford saw fit to mark EXACTLY where you need to cut on the back side of the bumper! Plus, all needed hardware & instructions are included.

Start to finish, this install will take you a couple of hours & the only specialty tool needed is an air powered body saw (available @ Harbor Freight, Sears, etc.).

This diffuser/valance will greatly improve the rear appearance of your 2013 Mustang GT or 2013 Mustang V6!
