      Looks better than it fits

      They should have been stock from Ford. They look great and went on super easy. I'm not sure if it's the Ford performance hood struts or the covers, but my radiator covers are rubbing on my hood when it's shut. I put some Velcro on the hood but it's still rubbing when the hood is shut on both sides.

      MMD radiator extension

      They look much better than the frame rails and the quality is pretty nice as far as the actual parts are concerned, however the attaching hardware just rattles in the holes in the frame and the stock hardware you reuse doesn't fit real well either. So to me, they could have done a better job in attaching the actual parts.... like some actual screws and blind nuts.... I mean they are $120 for plastic.... but they do look nice

      Easy install, nice look

      Install took minutes. All necessary fasteners were included. Really cleans up the engine compartment in the front corners and blends well with the existing plastics.

      Rubbing of paint under hood.

      It seems like MMD just doesn't really care about Quality, these covers were hitting the paint in 5 different areas on the underside of my New car. I pulled them of after about 50 miles. I also don't recommend buying MMD's Ram Air hood scoops either, I sent those back as well. I asked AM for MMD contact info and they wouldn't give it to me, they told me to just send the items back. Will MMD ever really the changes they need to make?

      Very nice fit and finish. Came fast after ordering. Very easy to install in 15 mins. Can't go wrong with this and they really clean up the engine compartment with a factory look.

      What a difference

      Just put the extension covers on. They were an easy install. I didn't secure the back edge with the 3m tape. At this point in time I see no reason too. However if I do it'll be with velcro. I want to be able to take them off easily if the need arises. They definitely complete the look under the hood. I have no complaints. They may seem pricy to some. However if I want it. I'm going to get it. This will be my one and only show car. Only the best for my Stang. Add the strut covers, which I did, and under the hood looks finished. After I put on the SR Performance Strut Tower it will look incredible. I'll undate with a picture at that time.

      Looks great, Fitment not perfect

      These look great when on, however the fitment is a little annoying. You need to use 3M tape to keep the very back stuck down, which would make them unremovable. Instead I left that off. The second plug they give you is way too small for the hole it goes in, so it doesn't hold it great either.

      Radiator Extension Covers really clean up all the exposed metal braces and gives the under hood that finished look. Would highly recommend for any showing their car.

      Radiator Extension cover, 2017 Mustang GT

      I'm pleased with the fit and look but there were NO Grommets that came with it. I had to go to my body shop where I've had work done in the past--they installed them with the correct grommets for free. Shame on you, American Muscle for not including them in the package! What's your excuse?

      Cleans up area nicely however

      These look nice and install in seconds, the only issue is they lightly rub the under side of the hood. I still use them , I placed some clear tape on the hood in the areas they rubbing on.
