Any difference in sound with it off?

I haven't done it myself, but I hear it amplifies the DI noises in the Ecoboost...as does removing the plastic top engine cover.

They don't have those listed on the website, give them a call or send Jennifer an email and they will hook you up.

Thanks Bill, U da man

Is there still the Mustang logo under the headliner ?

No pony logo under hood liner on 2018 (at least mine doesn't have one when I took it off).

I'm afraid the running hosre doesn't look as good on the 18 as it did on the 15- 17

Is it painted under there?
Also wonder how this effects open cai like Steeda or jlt seal to keep hot air out?

Removed it from my 15 and I was running a steeds intake, zero difference in hood temp or intake temps.

Is there still talk that's it's some kind of fire retardant material? Supposed to reduce the spread of flames/heat somehow?

I recall reading that, seeing a lot of people say that's bunk, the noise suppression angle makes a ton of more sense.

Love the logo, I've seen a vinyl kit that highlights it.

That is my understanding of what they are. As they heat up it will shrink and fall off, smothering the fire.

That is why older cars tend to have them hanging off - the heat cycles start to get to the pins holding it in place.

Im am sure it doubles as a sound suppressant.

There's no doubt that that's the main purpose. That's why it's held by plastic push pins. If there is a fire, the pins melt, the liner falls on top of the engine to try and help smother/isolate the fire. In terms of it being there to deflect heat, I ran my last one without it and never had an issue, nor have other people.

Now say you had an engine fire, i'm not sure if insurance could try to screw with you if they found out that you had removed it.

No it is sound insulation only. We had some NVH engineers at a club meeting and they confirmed it - even said that blanket itself is flammable.



And think about -- no one who makes this claim can find even ONE example of a car that was saved by the blanket smothering the fire out of all the engine fires.

Yep, that's why I mentioned my last batch of research seemed to confirm it was kind of an "urban legend", aka bunk.

I've read several posts that there are a number of cars without any kind of liner, so if this was something that was really an effective safety mechanism, I can't image it not being on all vehicles[?]

The bold sounds like pretty solid confirmation about the design intent of the liner.

My only concern is the direct heat from the engine affecting the washer fluid lines but if others have no issues then it's nothing to worry about.

If anything it would give you an extra 5-10 seconds to get out of the car. With it in or out it will be a total write off in a fire . Insurance isn't going to care.

In the audi realm it serves as a fire blanket, and has been documented to 1) increase turbo noise and 2) work as a fire blanket during an engine fire. :shrug:

The bigger question, I don't think anyone has pose yet, why remove it?

Add lightness :lol:

Expose the hidden pony logo ?

 

[Blue Moon]

Has anybody noticed any more noise with it removed?
