Hood Insulation

[Valsport]

Does anyone know the part no. for the insulation that goes under the hood? Mine is just nasty dirty and I want to replace it. 2001 silverado z71

I've had mine off for about a year now and haven't noticed any noise or heat change at all..

 

 

If it's gonna get hot enough under there to do any damage it'll melt all the underhood plastic before destroying the paint on the hood.

It's purpose is if there is an engine fire, the "snap's" that hold it on will melt and the stuff will fall on, and hopefully smother the fire
