Hood insulation, what purpose does it serve?
My hood liner is a bit dirty and is no longer aesthically pleasing to me. When I was younger I had the same issue with a mustang and just ripped it off with no detrement to the hood or car. I am a little less likely to rip it off the Z, but honestly, what purpose does the hood insulation serve? Is there ANY reason not to simply remove it?

Normally, a hood pad helps absorb a little of the engine noise. On the Z, I think it is so hard and thin that it really serves no useful purpose. I removed mine and couldn't hear any difference in sound. I put mine away and saved 681 grams from the front of the Z. Win/Win for me.

Those hood liners are also designed to suppress engine fire. The fire melts the tabs and the liner drops onto the engine giving the passengers an additional few seconds to escape.

Also not sure about everyone else, but my liner sits right on top of my intake and other parts (I can see their impression on the liner), so not sure it can drop down any further as they are already sitting snug on top of the intake. Also there are like 8 plastic snaps about the size of a silver dollar, which would take quite a while to completely melt away (which I would be long gone out of the car by then). I am going with the sound deadening.

I know on my stock Turbo charged cars, the hood liners were very thick, and almost always made of a foil type material.

While I agree this makes some sense and totally respect your input, then I would ask why is it that many cars don't come with them? My buddy's S2000 (honda) doesn't have one and neither does my friends truck.

he is right about the liner helping to supress the fire when the retainers melt and it falls on top of the fire. Many other cars do not have them because they have metal hoods and will keep the fire contained much longer. Here is proof of that. Car is at our shop right now. It caught fire and the insulator did what it was supoposed to and bought some additional time. You can see that eventually it burned through the hood, but it slowed the fire significantly.
Under the hood.... You can see the insulator "melted" to everything on the top of the engine.
the outside of the hood after 10 minutes of fire.
