Underhood blanket

Thought you newer owners would like to see this. Hummer only had them available for a short time.
Yes this is\was an official Hummer accessory. The underhood blanket.

What was the purpose of this...keep the engine warmer for colder states ?!

No real purpose other than sound insulation. It looks better than naked metal. And was quite common on older cars

I wish they had one for the H2! The stock one is pretty thin and useless!

I imagine it's no different than other cars. Supposed to be a fire suppression blanket. Under high heat the tabs melt off and the liner falls onto the engine in an attempt to suppress an engine fire.
At least that's how it was explained on my Subaru. It also acts as a sound damper.

On the H1s it was supposed to help quiet the diesel motor. May have been aftermarket only. I never actually saw one installed.
