Wierd yellow material under hood?

Im guessing this is to keep the heat from the engine off of the hood, but can it be removed without hurting anything? Because I think it looks like shit, so if I can remove it I will. Unless it serves a good purpose..

 

Helps keep engine noise down. It should be easily removable, I've replaced one on my parent's minivan.

 

mine was falling off so i took it off like 1 year ago... I dont have any problems from it.

 

Did you notice a difference in engine noise? Or not being able to hold your hand on your hood from being to hot after driving?

 

Yea this is the only vehicle I have seen this on.

 

Yeah, I have heard various melarkey about these before. My neighbor's Tacoma (pre-01) has one and I was puzzled. Othesr have said noise reduction, but I have also heard fire suppression, like if the engine catches on fire, the plastic tabs melt and it drops down to smother the fire.

Since I don't have one, I haven't bothered investigating any further.

 

That does make since. I might just keep it and paint it white with engine paint. Or remove it completely.

 

my truck doesn't have one
