Underhood insulation missing
I noted before that on my 2022 ZL1 (I took delivery on Nov.6 2021), there is no underhood insulation. I thought this is normal but then I saw pictures of ZL1s that have it. I read on GM Authority, that some were built without due to supply chain problems, does anybody know more? Can they get retrofitted?

When you say underhood... do you mean literally attached to the bottom of the hood? If so, I dont think that was ever included, at least not on ZLE

I have never seen a ZL1 with the underwood insulation.

Also, this would actually make less sense on a ZL1 with its high strung supercharger, hot engine bay and most people wanting to hear the S/C whine "unmuffled".

My 2017 ZL1 doesn’t have any under hood insulation and it’s stock.
