all that said, since i did the homework for this specific question i'll give it to you to see if others have any 2cents of their own:
Cobb Fiesta ST Intake System (everything starting from the upper housing of the filter box all the way to turbo inlet gets replaced. bottom stock filter housing stays in place. uses stock air inlet. filter box remains plastic. they have a carbon fiber alternative that is MUCH more expensive)
Mishimoto Fiesta ST Performance Air Intake (everything including the entire filter box all the way to the turbo inlet gets replaced. filter box is metal. also uses stock air inlet)
both systems are 2016+ compliant. be careful when looking though b/c i think at least the Mishimoto has a pre-2016 version floating around
