Factory AC or aftermarket ? Suggestions please

What was involved in the airbox rebuild ? I don't see parts on their website I'd like to find out what was replaced before I look around
Thank you btw

My box was in pieces when I got it from the previous owner. I ordered the DMT kit which includes mostly foam and sealing material, but It has a set of instructions that are so good it made my reassembly easy. There are no vacuum actuators in the kit, but I found that all mine were good anyway.
