      so fresh and so clean, clean

      If cleanliness is next to godliness, then this is the 1st step you should take to making your Mustang worth praising. It makes a world of difference and not difficult to install at all. Highly recommend

      Great Product cleaned up engine bay, I was hoping for a pre-painted version, but I like the matte black look matches all under the hood. Glad to see MMD come out with this. Thanks AM

      Clean Finishing look

      Product was a nice finishing touch, I was a little skeptical but glad that I got. There are a couple of small imperfects but definitely not show stoppers, 1) the color finish is slightly a shade different that radiator cover (factory), 2) height causes a little interference with hood rubber bump stop factory settings, when you raise their level the requires a little more resistance to close and again slightly rubs hood underside (clear film in the touch points will correct. By know means are these deterrents to buy, just observations. Really a nice clean German style engine surround. I would definitely do it again. -cp

      Engine Compartment Finished Look

      I always felt the engine compartment had an unfinished look with the engine cover, radiator cover, and nothing to cover the exposed sides. So easy to install, I had them in place in 5 minutes. Most of that time was cleaning the area before install. The look like they came from the factory with the car.

      MMD has done again...

      Like most of MMD products, it seems like an OEM part, absolutely recomended if you give importance to your underhood. It will be more clean and get a better appearance than stock. 4 stars because, like other MMD products, it's a bit overpriced but very happy with my purchase.

      Excellent fit and customer service

      Was very easy to install, however it came with only 3 of the 4 retainer pins that were loose in the box. A little disappointed at first but sent an email and MM promptly sent the pin I needed. I am posting a picture with the covers installed. Thank you customer service!

      Complements my other American Muscle engine compartment dress up. The install was easy and I highly recommend this addition, especially if the car has the radiator cover in place.

      The extension covers look fantastic. Cleans up the engine bay nicely. Plastic is a bit thinner than other underhood parts, but it blends identically to all other parts. Very happy with this purchase.
