I dont really know what its called so help me out but its like a formed peice of hard carpet that goes under the hood and fits over the engine to keep everything clean. Anyone know what its called and/or where I can get one?

It's called a hood liner, and it's primary function is to keep the hood from getting too hot and damaging the exterior paint. A side benefit is to help NVH. You will have to get this from an authorized dealer.

its also a fire blanket. if there is a fire it will melt the plastic tabs and smother the flames under the hood

It is not a fire blanket. It is sound deadening. The CR does not have them.

Helps keep hot air in the engine bay too. I removed mine a long time ago.

Why isn't it a fire blanket too? I work for vw and they do the same thing; noise, heat, fire blanket. Lol

Some under hood covers ARE fire blankets. I have read that the one on the S2000 is not.

What? No it doesn't "keep hot air in the engine bay". A full undertray with no venting would trap air, but not the hood mat. Air moves through the engine bay from the front to down and under the car.

Its probably for NVH more than anything. The paint on the hood is not in any danger from heat from the engine bay either, unless you get a fire in there. Once it saturates with ambient temps, its not going to shield anything.

As for the fire blanket part, I don't know. Of the few S2000s I've seen catch fire in the engine bay, it certainly didn't seem to work.

Considering its not on the CR, its probably just sound deadening and was deemed unnecessary by Honda for the CR model.

I agree that it's probably for NVH, but I can't imagine that it wouldn't reduce heat transfer to the hood. However, whatever heat transfer it might prevent, it surely less than the amount gained by driving the car instead of letting it bake in the sun.

yeah it does actually. Prevents it from rising up through the hood. Similar to a vented hood allows more of the hot air to rise out. That blanket keeps the heat inside.
