Hood-Insulator
I have an 07 tl and have been looking to buy a new hood-Insulator but haven't had any luck finding one for my 07. Would anyone know of a place or website I can buy one. Many thanks.

Just remove it. That was the first thing I did on mine, literally the second I got home from the dealer.
Otherwise go to acuraoemparts.com

Agreed, not sure why you would remove that. Doesn't it protect the hood and paint from high engine compartment heat?

Several of us have removed it without any damage or impact to hood or paint. Should also help cooling through the hood, and save almost 2lbs of weight, which is insignicant but still.

I remember reading somewhere that it wasn't insulation so much as a blanket to put out engine fires (i.e. if your engine caught on fire, the pad would fall off and smother it..?)

Not 100% sure, but I think the main uses for these insulators are sound suppression or as a fire blanket. It may help protect the paint on the hood as well long term, but it can also raise under hood temps, which will deteriorate plastic and rubber materials faster over time.
My last car was a turbo, which ran much hotter, and I had the hood insulator off for 3-4 years, no damage to paint whatsoever.
The hood and quarter panels get hot no matter what, even when the cars sit on the dealer lot under the sun for months until sold. Think Texas / Arizona / Latin america. Insulator does nothing there.
I took mine off primarily for better engine cooling, using the hood as a heat sink. The weight removal was a bonus.

Also conclusion of paper posted above:
Given that fire resistant under hood insulating panels were identified amongst
the small sample of vehicles examined, the possibility of the panels acting as a
fire blanket and smothering and engine fire is feasible. However, the
effectiveness of such a system can not be determined strictly from the component
tests that were performed. Ultimately, the typical temperatures of an engine
compartment fire need to be lower than the flaming temperature of the
insulation and higher than the melting temperature for the mounting clips.
Simulated engine compartment fires are needed to determine the actual
effectiveness of a fire resistive panel at smothering a fire.

Yeah they don't put out a fire, they just slow it down. Good for time to escape and fire dept to arrive. The plastic clips melt, blanket falls down and smothers things a bit. Happened to a friend of mine back in high school, while she was skipping lunch
Acura did a lot of NVH (noise, vibration and harshness) suppression on these cars, so I'd guess that is its main function.

Like I said, probably to keep the engine warmer longer (efficient to have less cold starts) and sound deadening. Good for the northerners, not so good for the southerners.

This question gets asked all the time and like others have stated, there is a lot of misinformation about it. It's primary use is to deaden the sound of the engine. It is by all means not used as a fire suppressant; some low end cars don't come with this equipped. It may help retain heat in the winter. It is also not used to protect the paint!

Yeah i was just about to mention the fact that all 3 Hondas that i owned previously did not have 1 either. I have been debating on taking mine out for awhile since when i got the car it has a ripped up spot where some insulation will dangle and I just push it back in, but man is it not the first thing you notice when you open the hood lol i hate it.

I've owned cars that didn't come with one too. The hoods looked better than the rest of the car by the time I sold each one

just replace it with a new one from any vendor here.

why honda decided to add it we'll never really know. without some kind of documentation, all we are doing is speculating, even if it makes sense. It's like, trying to put words in someones mouth just because we think it fits. They could have put it there for all the little reasons combined, and not any single reason alone.
#26
Not the case at all! I ask because I love the sound and hearing it a little more would be a bonus along with never having to look at the insulator again

For me the extra engine sound was barely noticeable. This car is very quiet on the stock intake and exhaust. Go for it

Mine had a top corner kind of bend after the engine was hosed down when importing the car.. Was starting to drop a little more every time I looked at it so I just removed it..
