    Review & Install Video

    Hey, everybody. I'm Justin with, here with some radical styling for your S197, courtesy of industry leader MMD. I'm going to be taking a closer look at the MMD Fender Vents, available for your 2010 through 2014 Mustang in your choice of either Unpainted, Pre-Painted, or Matte Black.MMD's goal is to help you separate your ride from the rest, and never has that been more true with parts like these fender vents. Now, these parts are definitely not going to be for the "less is more" crowd. Instead, it's going to be for someone who is not satisfied with the stock appearance and for the Mustang owner who is really looking to stand out on the street or at their next show.So styling-wise, what are we looking at? Well, as you can see, these vents do get installed behind the front wheel and in front of the door here, giving your S197 that race-inspired look. Now, besides those aggressive looks, the crew over at MMD actually claims a little bit of functionality with this part, acting as a heat extractor, allowing any hot engine bay air to escape through the vents here.Construction-wise, here's what you're going to be looking at, guys. Durable, automotive grade ABS plastic for the build, more than capable of handling the stresses on your track toy, show car, or even your daily driver. Now, as I mentioned at the top of this video, you do have a few options in regards to finish, starting with our pre-painted version here. Now, this version does get sprayed right here in AM in our state-of-the-art paint booth, using the same base and clear coat that Ford uses on their Mustangs. In addition to that, we are offering a matte black version, which is a good way to mix up the look a little bit, if that's what you're after. Finally, if you're looking to save a few bucks, we do offer an unpainted version, if you have a paint hookup or if you're looking to spray this thing yourself. As for the install here, well, as you might expect, guys, there is a fair amount of cutting going on with this job. So for that reason alone, I'm going to give it a three out of three wrenches on the difficulty meter. Now, you could probably do the job with the fenders still on the car. But personally I would recommend removing the fenders, first, it's really not all that hard, and ultimately it's going to give you the best result. Now, if this is something you're not comfortable with doing, definitely don't hesitate to reach out to your local body shop on this one. Or if you will tackle this one on your own, just figure about six hours or a half a day in the garage to get everything knocked out.So if you're looking for that aggressive race car styling for your S197 with a little added functionality to boot, then be sure to check out the full lineup of MMD Fender Vents right here at

        I have a V6 Mustang with the Pony Package. I have the Pony logo on the side fenders. If I install these vents, will I lose the room to also mount the Pony logo on top of the vents or will the logo no longer fit?

        • I've been pondering this myself. you could re-tape your pony emblem and install it onto the new vent, but you will have to place it towards the rear edge of the vent before it starts to curve inward. I've seen 5.0 emblems mounted in the center of the vent and it looks strange to me. the pony most likely will look better than that, because it is more vertical. also, you will probably decide it may look to crowded with the emblem on the vent since this vent is already a gorgeous thing to behold on it's own. i posted pics of my silver 2012.

        Should I be concerned about anything like rain water getting into these?

        • no problem, the area inside the vent is already exposed to the elements through the door jam and windshield drainage anyway, so no new threats will come from these. my car is not garaged, and driven year round. i had mine on for a couple years now, still my favorite appearance mod from AM that i have done so far. good luck with your 'stang!!

        How much will it usually cost if installed by a local auto shop? I heard it will take around 7 hours on average to install these. But I am not sure how much a mechanic charge to install these.?

        • Unfortunately, this the overall cost is going to vary depending exact who is installing it and how much their hourly charge is. These vents will on average, take about 6 hours for installation.

            Coyote vents

            They look fantastic! Glad I bought them. Fitment and install not a problem. If you are going to do vents, these are the best looking IMO, and functional! Keeping engine bay cooler never hurts.

            Serious Style

            Let's face it - there are only so many things you can do with your vehicle. This item fit my budget for the intense change it brings to the vehicle. As any picture, it can't really capture how awesome it looks in person. As it's not just layed over the fender, and is installed by cutting out a part of the fender(s), it really becomes part of the vehicle. Great buy.

            Great looking part

            Made my car look more aggressive. Love the way these vents look. Its scary at first if you are installing this on your own but its very easy just take your time. About half day job

            Great look!

            I love the look. Makes my car look so mean. The fit was great, but it doesn't come with a stencil so you really have to place your marks in the right place. There are instructions with pictures so that helps. All in all a great mod if you want to change the look of your pony, and functional to boot. I put down an afternoon, but the total install really only took me a little over an hour. I've done the hood vents so I had a good idea of the process already.

            Very nice addition, got many looks

            I gave this for stars instead of 5 because I thought they should have included a template to trace, aND a screen for the vents to keep critters out. Overall for me I found it easier to do the cutting and installation with the fender on. I actually had more problems removing the fender on one side risking scratching it and the other side I didn't even bother trying to take off came out perfect. In fact the biggest issue I had was whether to paint them or not.

            Scary, but easy install

            Removing fenders and cutting is a scary thing as there is no going back, however, everything went very smooth. Job was completed easily in the estimated 6 hours. Disappointed that "5.0" emblem glue marred fender vent plastic though.
