        Looking sharp!

        I have not installed this as a DIY so I cannot comment on time to take for installation. I sent it to my favorite body shop and they installed them for me. CAR LOOKS SHARP! I hated those factory honeycombs. Fit is good, cleans nicely and it now takes only a minute instead of close to an hour!

        MMD grille

        Looks awesome on the car. I get compliments on how good it looks. There is a slight gap on the left and right side of the grille but you only notice it if you look close (upper grille) bottom grille has perfect fitment.

        Some minor difficulty getting all the clips to snap in, might be my lack of experience but acted more like a fitment issue. On both lower sides, there is a gap that should not be there and for a detail oriented person like myself, glaringly obvious.

        2 2018 GT - DaveO


        I ordered this for my '18 GT and installed it with help from my mechanic in just over an hour. I noticed that on the passenger side, there is nothing between the triangular opening and the metal frame behind it, so it looks like there is something missing. I contacted AM and was given some mumbo-jumbo told it would be 'fine.' It's NOT fine! Not sure what's going on, but at the Ford Nationals in Carlisle over the weekend, I inserted a piece of black construction paper so it wasn't so obvious! Not happy! I am normally very pleased with products and service, but not this time.

        Look excellent

        Looks great except sides of upper have gaps. Lower fit way better tabs were a little difficult to get hooked but to get bumper off was very easy

        4 2018 GT - Cruising18 Installation Time: Afternoon

        Nice looking, but could be improved

        The MMD grille is an easy way to increase the sportiness of your mustang while also omitting the pint in the center. It does increase airflow to the engine as well. My only disappointment is the upper grill is not quite as wide as the original leaving some gapping in the sides if you look closely.

        4 2018 GT - BluS550 Installation Time: Afternoon

        Almost perfect

        Used to have the MMD V-series grille for my 2017 ecoboost (some one ran a red light and totaled my car RIP) , so when I got my 2018 GT, I knew right away I wanted something similar. I couldn't find anything for a while and then one day it just popped up on American Muscle. Got it as soon as I saw it. What can I say? It looks amazing. It gets rid of that stock mismatch between the upper and lower grille, and also eliminates the pony - which I am not a fan of. The paint job on it seems great. It's not gloss black, but it does seem darker than most matte black plastic pieces, which makes it look better, in my opinion. It was also a pretty painless install; everything went in like stock. I didn't even have to remove the shutter system like most of the other grilles require you to. I didn't bother because it wasn't part of the instructions. Not sure if I'll regret that later or not, but so far no issues. One thing I will say though is that on the upper grille there were some fitment issues on the nose openings, or whatever you want to call them. If you put your face near it and look closely around the edges of the openings, you can see the plastic alignment clips do not fill the entire gap. Nothing I care about, personally. However, if you're OCD about these kind of small details, it may bother you. It could also be possible that you may not have the same issue as me. Overall, I highly recommend it. It's the best looking grille option to me.

      Am I the only one bothered by the gaping hole on the passenger side of the upper grill behind the "triangle" in the corner? I gave this a poor review because of it. Liked it otherwise. Is there a solution to this?

      Will the lower grille work with adaptive cruise control?

      • No, the MMD lower grille will not be with adaptive cruise control.

      Are you able to keep the grille shutters with this grille on the 2018 ecoboost?

      • This will not work with the grille shutters no.

      Would you be able to reuse your emblem if you still would like to and be able to mount it on this grille? I know the grille is supposed to be emblem delete style but I really would love it if you could still mount the emblem back on.

      • The factory emblem will not be compatible. You'd need something like an emblem intended specifically for use with a billet style grille. It would be designed to reach through the grille and clip onto the back. We have not tested a particular emblem with this product and are unable to provide a recommendation ourselves. This item is designed to delete the pony emblem.
