            18 test fit

            I really ordered these to get an idea why the description stated only 15-17. No one was really able to give me a solid answer as to why these wouldn’t, so I bought a set. I can now confirm they “may” fit an 18 with a 15-17 front radiator shroud and some drilling to the extension panels... but these are not nor will not drop into place on an 18 . However, quality was good, shipping was fast and packaged well as to not damage the items. Felt as they were the same quality as the OEM front radiator cover to give an idea of feel and look.

            If you don't mind the rubbing against the hood...

            Not really thrilled with these. They do make the engine bay looks much nicer/cleaner. But they didn't do a good job engineering these to avoid contact with the hood. As you can see in my photos, there are several spots where it rubbed the paint off hood and caused defects in the covers. They should have included rubber pads to place on the hood in these key spot. Next, I had to remove them for some work and the "pins" that secure them, the smaller ones, the tops popped off. So now they are broken and I can't reinstall the covers until I can replacement pins.

            Engine cover extension

            Piece looks nice but does not hold great following directions on how to install but the one clip provided holds okay but the clip from on original place in car and instructed to put in new slot does not hold correctly. Now I have to go to ford to purchase a bigger longer clip to fasten it down for both covers I purchased

            Great looking addition under the hood.

            Great looking product, as long as you don't have the Cervini's ram air hood. The hood has additional support coming down the sides making it thicker in depth there for hitting against the covers. Oh well...

            It should have came from Ford with this.

            Looks totally factory and easy to install. I like that it now comes with Velcro tabs on the ends instead of permanent glue down tape. I will no longer be dropping my tools into my fender. :)

            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
