Any reason not to remove my surfboard sized engine cover on my 5.0?

[2022 Mach 1]

I got a refund. We agreed mine was faulty, the tune or readings that came with the box. But, when it worked you really could feel the difference compared to stock. This is my thread I started when things went iffy with the box.

After returning to stock things were normal again. Steeda gave me just a tune (no CAI) I was happy with until I upgraded.

Thanks for the reply. I read the link. Good info.

I removed my cover shortly after bringing the car home. The oil fill neck can be removed, then you can add the fill cap directly to the valve cover. I just reinstall the neck when I change the oil, since it is easier to pour oil in with the neck in place.

How do you remove that filler neck? I tried twisting counter clockwise and it felt like it was gonna break so I stopped. I want to take mine off too

It's the same as the fill cap, 1/8 to 1/4 turn counter clockwise and off it comes, then you just put the fill cap in its place.

I took my cover off cpl months ago. Like the way it looks without it. Oh and Selma lost about 4-5 pounds

There must be a reason the engineers put that cover on. Can't just be cosmetic. Has Ford ever talked about it?

It’s definitely purely cosmetic. I thought maybe it was to dampen some engine noise as well, but it’s just plastic and has no acoustic properties. I also doubt there is any heat benefit either.

Maybe it's a cover to prevent dust/dirt/corrosion?

Sometimes it does break, there's a little locking nub. Mine broke off. Make sure it doesn't fall into the valve cover (the cover's tabs wont break, so no worry there).

The problem I have with removing the cover is that I find the engine even uglier without it. All you can see without the cover is a chaotic array of cables, pipes, hoses, connectors, all mixed together in an incomprehensible mess. It looks like Rod Stewart's hair.

I kind of agree, but the intake manifold looks nice. I just removed mine since it doesn't serve a real purpose, traps heat over the coils and for many different mods/repairs requires removal as a first step anyway, lol.

I'll give you that the manifold does look nice, indeed.

I noticed lower cylinder head temps when I pulled mine off. I usually sat around 210, give or take, now the car comfortably sits around 196/198 unless I'm idling for a while.

^^^Well that's just a bonus!!

Not really. The engine runs more efficiently at a higher cylinder head temperature. What benefits do you think a lower temperature would provide?

That being said, mine came off in the first week, because I prefer the look without it.

Yea, you can't put your beverage, sandwich or snacks nearby when working on the car....

Yeah I’m gonna leave it on lol, it doesn’t bother me that much
