what is this next to my intake pipe and turbo inlet

[thorcc]

pretty simple. what is the tube with the white cap next to my intake and coolant reservoir. found it while upgrading to a kn intake since oem engine air filters seem to not exist. if it is what i think it is then more nonsense from dodge/jeep on making these vehicles unworkable on your own. Edit: found the part its slotted in to at least item 10 here https://store.mopar.com/v-2021-jeep...ation-service-engines-and-engine-service-kits but still no luck finding "it"

Looks like a transmission vent tube. Pretty sure my 2014 ram has it also. No idea truly though
