    Are these available painted to match factory colors

    Will this be compatible with a Hellion twin turbo kit? I’m trying to hide the empty space near the relocated coolant tank. Thanks

    • The MMD Radiator Extension Covers have been installed on supercharger and turbo applications. However, we have not tested these covers on a twin turbo set-up which could potentially have some clearance issues on the passenger side turbo.

      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?

      Radiator extension covers

      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?

      I was looking for something to finish the work I have done under the hood of my mustang. This product was perfect and gave it the over the top finish it needed.

      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.
