    Hey, I'm Justin with and I'm taking a closer look at MMD's classic quarter window louvers, fitting all 2010 to 14 Mustangs, available in your choice of either unpainted or pre-painted. If you're looking for a retro or modern styling part that's going to separate your ride from the rest, look no further than MMD. They've quickly become the industry leader in producing cool and stylish appearance parts for mustangs of all ages. Now, if you guys want to see more killer parts from MMD including some of their wheel offerings for the S197, go ahead and click on that link below to subscribe to our YouTube channel if you haven't done so already. So the classic quarter window louvers from MMD are definitely one of the more popular appearance parts here on the site and are, of course, inspired from the iconic 60s Fastback Mustangs. Now, thanks to the retro lines of these modern S197s, the louvers look right at home here on our 2014 GT. Taking a closer look at the louvers themselves, you'll notice that MMD went with a lightweight yet extremely durable ABS plastic for the construction, all of which have been injection molded making for a perfect fit and finish. As I mentioned at the beginning of this video, you do have the option of grabbing these louvers unpainted, or for a few bucks more you can spring for the fully painted version shown here. Now these louvers are sprayed in our state of the art paint booth at American Muscle headquarters, making for a perfect color match right out of the box. Now guys, go ahead and click on that link below if you want to head back to the product page at for a full breakdown of all the colors available for this louver. Included in the package, you'll find everything needed to install the louvers, including the 3M automotive dual-lock adhesive tape, which basically allows you to remove the louvers after they're already been installed to clean the rear window. Now for the install itself, you'll first want to clean the backside of the louver and the quarter window using the alcohol prep pads. Grab your adhesion promoter and then wipe down those same areas. Install tthe 3M automotive tape to the backside of the louver, remove the protective backing, and adhere the louvers carefully to your ride. Getting everything installed is only going to take you about 30 minutes from start to finish but if you should have any problems with the install or if you just have any questions, you can always get in touch with one of our Mustang experts. If you're looking to add iconic 60s Fastback styling to your 2010-2014 Mustang, then be sure to check out MMD's classic quarter window louvers available right here at

        I assume these aren't meant to be removed, so is there any way to clean the quarter window glass with these on? I'm worried about stuff getting inside the louvers and building up over time. Also, if I ever needed to remove these, could I do so without damage/leaving marks?

        • Actually, they are made to come off so you can clean the quarter window under them. At least, mine were. The install strips were a type of Velcro and the guy at the dealership just forced them off, cleaned the window, and put them back on. I was afraid I would screw something off so I paid the body shop 20.00 to pull them off, clean the windows, and put them back on. Usually about once every month or so and I had the car for 19 months when I traded it in on a 2016 and they still were holding fine. I had the body shop at the dealership install them so they were familiar with how they worked. You might check with your dealer and see if someone there know how yours work. Hope this helps

        Can you see out of the window with type of louver on the window? I want to purchase them because they are cool looking and make my Mustang look even better, but if it is going to hinder my vision I will pass and purchase other stuff for my Pony.

        • Yes you can still see out of the window. Inside the car they are angled to give you some visibility. I was concerned too, that is why I didn't get the blackouts. You will also start using your side mirrors more, which is a good thing.

        This might be a dumb question but what color does the louvers come in if its unpainted

        • There is no such thing as a dumb question! These unpainted louvers will come completely un-finished with the raw ABS plastic material. The material in a dark charcoal black color which you can see from our other product photos.

        The video mentioned taking these off periodically to clean the rear quarter windows. Can these be put through a car wash?

        • I just traded my 2014 GT for a 2016 GT but I have mine on the 2014 stang for a year and half and it went thru many car washed and never came off. They fasten on with a Velcro type of thing and you can pull them off and clean the rear quarter window and put them back on. I always had the dealer to do it when I got an oil change but I watched them do it and it didn't look very difficult. A little pull pressure to get them off and make sure they were straight going back on and all was good.

            Great styling for the money

            I’ve had these louvers for roughly one year and I can say I would recommend them to anyone. The 3m adhesive has not budged one bit, and the paint is still pristine and matches perfectly. Definitely a nice little mod for the money.

            Wanted a sleeker look for my quarter window louvres, so I switched to these. Look a lot nicer, and aren’t as obtrusive I’m my side mirrors’ view. Great product.

            There were a breeze to install and really added a sharp look to the car. We installed them in about 15 minutes. I would recommend these louvers to anyone. You do lose some of the visibility through the window while driving but can see through the slats.

            Awesome Father's Day Gift!!!

            My kids got me a set of these for Father's Day 2019 already painted in Deep Impact Blue to match my car. The paint finish is excellent and matches the car paint perfectly. The installation kit comes with: 4 alcohol prep pads to clean and degrease the windows and louvers. 2 adhesive promotion pads that you wipe on the mounting surfaces of the louvers and windows. And 12 3M "velcro" adhesive mounting strips to secure the louvers to the windows. They took about 20 minutes to install and, in my opinion, dramatically change the appearance of the car! I would HIGHLY recommend these to anybody who loves the vintage 60's fastback look!

            Top gun purchase!

            Easy install, looks fantastic. Has that cool old muscle car look and the fact it attaches with Velcro so I can clean the glass from time to time is a bonus. Painted at AM and looks like it came with the car. I highly recommend these louvers if you are looking for a set.
