            Here’s my review.

            While purchasing these covers I said I would post a review for them. I just installed them and they seem to work perfectly. I raised my bump stops for hood to a higher height to prevent rubbing, time will tell if it’s rubbing, if it is I will simply put a couple felt squares on roof of hood where they touch.

            Nice quality and perfect fit!

            Picked up a set from AmM as I felt the Mustang's engine need a bit more covering. Shipping was decent but was very happy with components. I had a local shop, JackThaDipper, hydrodip these 2 panels plus the radiator support cover in an Autism Awsreness theme. The result was amazing and extremely well received from the Mustang community at a couple local shows. See more pics on our IG @eco4autism. We show in support of Autism Awareness.

            Totally love this addition to the engine bay. Installed in less than ten minutes and completely changed the look under the hood. The best part was, I ordered them on Wednesday, and received them Friday !!!

            NEEDS A LOT OF IMPROVEMENT

            I BOUGHT THIS AND IMMEDIATELY NOTICED IT RUBS AGAINST THE HOOD TO THE POINT WHERE IT RUBS THE PAINT OFF THE HOOD. I WOULDN'T RECOMMEND BUYING IT AT THIS TIME UNTIL THE CORRECT THE PROBLEM. IT WOULD BE GREAT IF CORRECTED BECAUSE IT DOES FINISH THE ENGINE COMPARTMENT

            Radiator Extension Covers

            They look good but do rub against the hood in several places. I used 3 plies of yellow electrical tape to make small pads that blend well with hood.

            Won’t work with aftermarket hood

            I have a cervini hood and the fitment is off, the aftermarket hood has different bracing that hits causing the hood not close properly. Looks amazing wish it worked, starting return now.

            Good quality fit could be better

            Original order came with two left side panels, kinda hard to make that work. They were quick to send out a replacement and install was easy. They DO rub on the underside of the hood in several spots I put small clear rubber bumpers on the hood and that eliminated the rubbing but not before it took the paint off.

            Radiator Extensions

            I really like how the Radiator Extension Covers give the look of the Engine Bay being clean. The only draw back is they sit a little high so I have to take them off when closing the hood, otherwise they wear off the paint of the hood where it hits the extensions.
