    Hey, guys. Stephanie with AmericanMuscle.com, here with my review of the Cervini's Quarter Window Louvers for all 2015 and up S550 Mustangs. The Cervini's quarter window louvers are a good option for the guys out there that like the look of an aftermarket, old-school inspired exterior appearance. These quarter window louvers are a quick and easy way to enhance the exterior appearance of the S550 in a non-permanent way, so it's a good option for those owners that are looking to just add a little something more but that aren't looking to get crazy modifying. Cervini's gave these louvers a different kind of look than the tradition louver and I say this because they are less boxy. They have an old-school design that doesn't really pop off the car much and that's going to give them a different type of appearance. They look a little bit flatter to me than the Roush window scoops and even though I think that the MMD by Foose window scoops are sleek, they still box off the window and so these are a little bit sleeker, in my opinion. So you can see, these have a stepped louver design which is a throwback to the '60s and '70s and resembles rear window louvers. These also have a matte black finish, which is nice because the finish will work nicely with any color Mustang, and they're also going to blend in with the window trim so they're going to look more like they belong. And if we look at some of the small details here, these lines in the louvers really work well with the line in the window trim, so this is all going to blend nicely together and give a clean look. The other thing to consider is that you can always paint match these if you want, as long as they're properly prepped. They're made from an OEM-quality injection molded polyurethane and Cervini's uses this material to give the product strength and durability so it can hold up against the elements. One thing I will mention here is that the backside of these aren't necessarily pretty. So if you're worried about seeing the backside of these from inside the car, you can always grab some quarter window blackout decals to hide the backside. The blackout decals cost $25 and they're just a little styling upgrade if you're worried about the look from inside the car. As far as price, you can expect to spend right around $300 for these louvers. These are currently sitting in the more expensive slot as far as unpainted quarter window pieces go, but like I said, these are a different look and you aren't going to have to worry about painting these before installing. They're also a Cervini's product, so you know you can expect a great fit and we'll show you just how well they fit in a minute here. Another great thing about these window louvers is the install. I'm not sure it can get any easier than this. You're looking at spending about a half hour and I'm going to call it a one out of three wrenches on the scale, even though you won't need any tools to get this done. These come almost ready to install right out of the box. You will need to put some 3M on these yourself. The only other way this could get any easier is if they had the 3M tape pre-installed on the back already. To start the install, since these do install onto the window and not the body, you are going to want to make sure that the windows are as clean as possible, and I'm talking no bugs, no grime or any of that. Once the window is clean, apply the 3M tape to the back side of the louver. You're going to want to put the tape on the flat contact areas on the louver. After the tape is installed, remove all of the backing and line the louver up with the rear corner of the glass. Then line the louver up with the top trim while still holding the bottom corner away from the glass. Then attach the bottom and front of the louver to the glass. You really only have one chance at lining this up correctly so just make sure you take your time. Once everything is lined up, press firmly on the louvers in the areas where the tape is touching the glass. You want to make sure that you create a good seal here. One other thing to mention here is that you should allow the tape to adhere for 24 hours before driving the car. If you don't let it sit, the adhesion could fail and you could be looking at your louver taking flight. But that's it as far as the install. But if you want to take a look at the fit, you can see that these things do fit very nicely. Wrapping things up here, the Cervini's quarter window louvers are a quick and easy way to do some exterior mods and add some more style to your S550. And they look great by themselves or paired with other mods. These are a louvered style in matte black and they're going to work on all 2015 and up Mustangs and you can check them out more online, right here at AmericanMuscle.com.

    Muscle Car Styling. Add the same intimidating muscle car styling of the 60's and 70's to your S550 Mustang with a set of Cervini's Quarter Window Louvers. These C-Pillar window covers feature a stepped louvered design that will give any 2015-2019 Mustang a more aggressive muscle car appearance.

    Polyurethane Construction. Cervini's manufactures their quarter window louvers right here in the USA from OEM quality injected molded polyurethane for superior strength and long lasting durability. Cervini’s then completes their Louvers in a killer matte black textured finish that allows them to be installed straight out of the box.

    Quick and Easy Installation. No messy glue or drilling is required for installation. Cervini's Quarter Window Louvers are designed to attach to the factory C-Pillar glass with the supplied 3M doubled sided automotive bonding tape for a quick and easy installation. Just clean the surface, peel the backing and stick in place - it's that easy.

    Recommended Styling Upgrade. When installing exterior quarter window louvers or scoops on your Mustang it is recommended to add a set of quarter window blackout decals to hide the ugly back side that wasn't meant to be seen by human eyes. See option above.

    Application. Cervini's Quarter Window Louvers are designed to fit all 2015 to 2019 Fastback Mustangs, including the V6, EcoBoost, GT, and Shelby GT350 models. Sold as a set of two, one driver side and one passenger side.

        Do these have slits that the driver can see out of? Or are they completely covered? If they're covered, are there any quarter window louvers that have slits that the driver can see out of?

        • Earlier I wrote to try Roush window louvers, instead try the Street Scene window louvers.

        Will these louvers fit a 2019 Bullitt Mustang...? My Ford dealer indicated that changes were made to the Bullitt trim on the window and they they do not fit properly ( stick out fom the too far ).

        After installing 10 months ago the passenger side louver came off. Do you have a single replacement or are they only sold in pairs?

        • We are sorry to hear about this! Unfortunately, these are currently only available in pairs at this point in time.

            Had for about a year now

            They looked super nice and clean when I bought them, despite the bad reviews mine have never fallen off but you do have to re-tape every couple of months. (also let set for 24 hours blah blah etc) although these aren’t very special and are just plastic, Cervini stands for there products and I do really like them!

            Not worth the money

            I've bought quite a few parts from American Muscle but unfortunately after losing the driver side louver and finding it several times it finally blew off again and couldn't find it. Worthless double sided tape was a bad idea to start with so unless you want to lose 250 dollars I wouldn't buy it.

            Louvers blew off

            Loved how easy they were to install. They look amazing on my Deep Impact Blue Mustang. Unfortunately, after like two months when I went to get my first oil change at the Ford Dealership, I noticed the driver side louver was missing. My car now looked ridiculous ! I called This company and explained the situation and basically. I would have to pay full price to get a new pair. I went to Cervini’s website instead and paid $250. I have the rear louver and that came with Adhesive Promotor . I bought some of that and put it on my new louver. On the 21st of this month the second louver blew off. That one has been on for close to a year. Common sense would be to add Adhesive Promoter.

            Expensive but worth it.

            It's not perfect; the paint job could certainly be better. What I find odd about Cervini's stuff such as these louvers or their chin spoilers is that their product is very rough to the touch. Some what like sand paper, in a way. Whatever you do, do NOT clean these with paper towels. It will tear apart the paper, and the paper towel particles will get stuck to it. Which brings me to my next point. They tend to stain pretty easily and look really bad when they aren't clean. BUT when they are, they appear as if they are a factory part. Literally one of the best looking louvers you'll find. They go along the lines of the quarter windows almost perfectly. I'd choose these over all the others any day of the week, despite the high price.

            Non-stick

            These looked great on my car for about a month. While driving on the freeway probably going 50-55 mph one of the louvers flew off the car. After about two weeks I managed to find the louver thar flew off. Went to hardware store found the exact tape that came with package and on my way home the other louver fell off to be run over by vehicles behind me. So for $200 they didn’t last. Wish there would have been some more sterdy tape or method to secure them to the car.

            This is one of best louvers I ever owned. I have 2016 Shelby GT350 and these make my car more sick. If you care for back seat vision don't buy it because it will block the small windows but who needs them.

            Loved the look these gave to my mustang. Was super excited for them but one day I got to work and realized my passenger side was missing. On the plus side my rear looks better without the sides but out of a lot of money.

            Love the look...but

            Love the looks of these. The mat black finish could be smoother, small little scratches show up when cleaning due to the texture of the material. Also, don't know if it's just my luck, the American muscle recommended vinyl blackouts or the 3M adhesive tape, but man oh man, the front corners want to lift up 24/7. It has become part of the routine to inspect them daily. I finally broke down and placed a bead of silicon to see if that solves the lifting problem for good.
