Gen 3 Coyote Engine Cover

[michail71]

I know there is the cosmetic and sound dampening debates that always go on about engine covers but this one on the gen 3 is just so odd looking with it so big and flat. The engineers put a lot of thought into this car and power plant so I'm thinking there must be a reason for the design? I can see the gen 2 as being more cosmetic.

If it were sound dampening I would expect some more insulation. There are some vents built in. If it were cosmetic I don't think it would look as ugly as it does.

If I knew the function I could perhaps love the form. Perhaps it's designed to work with the heat extractors?

I just pulled mine off and reattached the strut bar. Personally like to see more of the engine. Love the 4 cam heads.

It made no difference in sound.

The original coyote engine cover was nice, this one does suck. I dont know why they made it look so bad other than the HPFP makes weird zapping noises and they wanted to mask that.

I took it off today, which is a pain with a Steeda strut bar, to do an engine bay cleaning. Anyway, I don't notice any sound differences with it still off.

With all the work they did on reducing turbulence through the grill I was wondering if it had something to do with that.

It's just a dust, dirt cover. Shouldn't notice any sound differences

Not for sound, but for air movement over the engine...

Do you have any details? That hasn't been the case with most cars.

That goes a little with one of my theories it has something to do with the drag reduction features they have made.

Sorry to necro an old thread, but I'm thinking about removing it too but don't want to lose any gain it offers as Ford wouldn't put this big ugly thing for no reason.

I noticed that there a curve that tapers downward on the leading edge of the cover, that's obviously an aero design. I'm thinking it helps make good use of the airflow to the hood heat extractors.

If anyone has dealt with Ford engineers regarding, I really appreciate the input. I'm soooo ready to take it off.

It curves like it does to follow the contour of the hood. The only purpose it serves is to hide the manifold, harness, etc under it.

The Bullitt Mustangs don't even come with them. I don't think there's any issues with removing.

Yep, it's completely aesthetic

I took mine off a few weeks ago after installing a new intake. I hate the look of the thing and it weights about 3lbs.

I still think that it is designed to cut down the DI noise and direct the sound downward so the car sounds better. It is a pain to remove with those two 10mm bolts and plastic covers. I have to remove it to service my FP catch can.

i threw mine away. it's for sound deadening and looks, that's all

As mentioned, my Bullitt doesn't have it, so it's definitely not needed for anything functional. The only question is if it helps cut down engine noise inside the cabin. And THAT I don't know. With all the nasty noises these engines make, especially the annoying 2K rattle, I'd use a dB app inside the cabin in let's say, 2nd gear and 2,500 rpm (or whichever makes the rattle louder), cover on and off, and see what the difference in dB is. Then make the decision if you want it on or off. If there's no difference, then it means it's just fully cosmetic. I assume both GTs and Bullitts have the same full hood insulation underneath, to compare apples to apples.
