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!

  Amazing outcome!
By on 3/7/2014
Image uploaded by kaden g. I bought this couple weeks ago, got around to a install. The install is MUCH easier once removing the bumper I found out. There are pre-cut marks on the inside for anyone wanting to do this but scared to mess it up like I was, remove the rear bumper and cut along the already laid down template. I wouldn't go back. Absolutely love how much aggression it added to the back of my car! Couldn't be happier with the product, next day shipping, and outcome. Great job Latemodel Restoration!

  Simply a Must Have!

Image uploaded by Jake M. I bought this around 2 weeks ago, ordered on Sunday, arrived on Wednesday, installed on Friday. This OEM valance completely changes the rear end of the 13 and 14 Mustang and in my opinion should have came stock from the factory. It makes the rear look much more aggressive.
Only negative is that it requires some cutting to install properly, so take your time!!! Otherwise, I'm very happy with this rear valance.

  Boss 302 Rear Diffuser (13-14)
By on 7/6/2014
Image uploaded by Charlie Barone Jr. I have had one mod on the top of my list since I got my car. The Boss 302 rear diffuser. I was debating on doing it because it involved cutting into the bumper of my new Mustang. But I decided that I would take my chances. I had to remove the bumper cover of the Mustang for the installation. Removing the bumper also required me to take off the inner trunk panel, mud flaps and tail lights. Once removed I had to cut the bottom of the bumper off as well as cut slots for the tabs of the diffuser to insert in to. After the cutting was done I attached the diffuser to the bumper cover and put everything back together again. In the end it was all worth it because I love how it looks. It adds a bit of aggression to the back of the mustang as well as help it stand out from the crowd. I could not be happier with the quality and fit of this item.

  Great look and fit.

Without having the install instructions loaded on the page, I was unaware that installing this diffuser would require a bit of cutting. It sounds awful at first, cutting apart your perfectly fine stock bumper for the sake of modification, but was not that bad. Ford was kind enough to provide lines on the back-side of the bumper to show you how to do it and if you watch the Latemodel Restoration Shelby diffuser video, the install is roughly the same. Just be sure not to cut away too much material.
Fit and finish is great and it adds a subtle difference from your to all the other 13-14 GTs. Looks great with my Roush mufflers and 4 inch tips crowding the holes in the back for the exhaust.

  Awesome Aggressive Look!
By on 4/30/2014
Image uploaded by Matt S. Bought this diffuser because I was looking for something to spruce up the rear end of my '14 GT. All I can say is this diffuser certainly fit the bill! Came shipped and well wrapped in shipping tape etc. Came with the appropriate instructions and all mounting hardware like advertised. The only advice I can give to those who are somewhat concerned about drilling into your bumper is to take some painters tape and mark off where to cut with the tape and TAKE YOUR TIME. Being accurate and precise with the cuts will help you out a lot! Overall, makes an awesome rear end look even better! Definitely a must buy!

  Awesome Addition
By on 6/19/2014
First mod on the car, and it was definitely worth it. Adds a little something to the rear end without breaking the bank. As far as installation goes, removing the bumper makes it so much easier, and cutting is a breeze because of the lines on the inside showing you where to cut. If you're still unsure of yourself, there are plenty of tutorials on youtube and forums. Take your time cutting with a dremel, and you'll be fine. All in all, super happy with the purchase and customer service.

This makes the car look so much better. Aggresive but looks like stock. You will need to remove the rear bumper on the car to do the installation. Once you remove the bumper you will notice that the factory bumper has the exact lines and tabs that need to be cut. Follow the lines on what to cut and cut the marked tabs and the installation will go smooth. The necessary hardware is included .
Great look !!!!!! Definetly recommend the boss 302 rear duffuser !!!!

Image uploaded by Clovis purchased a few weeks ago, and waited like a 12 year old kid because I couldn't wait to slap it on my bumper. Over all, product is excellent. I couldn't trust myself to cut my own bumper so I had it professionally installed. I'm happy with the new aggressive rear end..

Image uploaded by Bradley Chatman The end result is well worth the agony of hacking into your perfectly good bumper cover. I will say though that the tabs around the exhaust tips were a little difficult to make fit nice and snug.

This Boss Diffuser really makes the rear end of my Ingot Silver Stang really stand with the contrast of the colors. Fit is great and the install isn't bad either.
