The small bulb shaped thing the yellow arrow is pointing to. 2020 M6 car. Mine is a 2021 A10 and it doesn’t have it. Also what part is missing from the air box to throttle body duct? Thanks

That looks like the sound tube. Basically a pipe with a diaphragm in the bulb part that routes through the firewall for engine sound. Looks like it got ripped off the intake. At a minimum you'll need to plug the hole on the intake tube. The sound tube doesn't offer any performance benefit so can just pull that completely or reconnect to the intake instead of plugging the hole. Whichever you do just make sure no air can get into the intake tube past the MAF sensor, otherwise you'll likely be throwing codes and running rough.

Side note, your coolant is pretty low. Want the top reservoir to be full and the bottom to be about half full. Bottom reservoir is filled through the tiny pipe on the back side of the whole coolant tank assembly.

correct. sound tube. when we added the GM CAI, we removed all that crap and plugged the hole into the firewall.
interestingly, our 2020 A10 had it.

Looks like your coolant is low also.

My 17' doesn't have that...or need it.
