There was a thread about 2 or 3 months ago. Lots of speculation but no definitive answers. Some thought it was to deaden engine noise, others felt it might help extinguish engine fires or insulate against paint damage.
Regardless, when I installed my Lingenfelter hood it came without a lining. So far I don't see the need.

I've never been in a meth lab so I dunno if mine smells like one. I did meet a chocolate lad once that smelled pretty bad.
The hood liner is there to be destroyed when your 05 has the crank bolt issue and it sings off at 120mph at the track and slaps the belt up against said liner making it look like a flock of birds exploded in your engine bay.
As soon as it removed all is at peace unless you have a meth lab on your engine. Or an onion sandwhich, then it might smell like an onion sandwhich when its hot.

The under hood insulation acts as sound deadening ( does not allow noise to be reflected ). It does not make a huge difference in sound but it does have an effect. You need a db meter to accurately measure the difference.

Forget the cosmetics I just want to know the purpose of the insulation and this goes across the board on all cars. If your insulation was falling off would you remove it?
Would you then replace it? Or not?
How much difference in insulating sound? I mean can you really hear the difference?
I thought it might have been for heat protection for the paint on the hood.

How long has it been removed?
Mine is starting to fall off.
If I replace it just the insulation piece costs $124.00
If it isn't safety related in any way or protects the paint on the hood I don't see any function for it. If it's for noise insulation only there is no need to replace it.

I don't know for sure but I've heard a hood-liner helps muffle sound; it's a heat barrier helping to preserve the paint on the hood; and, in the event of an engine fire the plastic retaining pins melt and the hood-liner drops onto the engine acting as a fire suppression blanket.
I seem to recall OregonC6 has strong opinions about the hood-liner or "mat" as he refers to it. Hopefully he'll jump-in as well.
The majority of cars I've owned have had hood-liners. I certainly see no benefit removing it. Besides, it makes a wonderful canvas for under hood artwork.
