If you still have the "snorkel" - the intake usually has a number imprinted on the plastic housing. look for the > PP - TD < and a "Ford" logo. The part number is in that area. You should be able to get that part from a dealer, or since you're on the internet - you can google a search for that part number.
That is, if you want a "Drop in" replacement.
If you're making a design change - then all bets are off. But I can tell you they did not make many changes when we went looking for 2018's and the 2019's mixed together. At least in the USA.
It is unfortunate they are closing down the line that makes these vehicles.
But what I can warn you about is; the design differences.
Just grab a "FRAM" or "Purolator" cross-reference book and you be able to take heart in knowing that the Air Filter, Oil filter - and Cabin filter (if you needed one) are the same. So that usually equates to the housings and the "footprint" it needs to function have not changed.
The 2019's are a "kit bash" of older stock and amortized-off leftovers. We witnessed it - for in our search we found a wide variety of features. We found a SYNC II vehicle but it used a "2017" whip radio antenna - while another in the same lot - also same year, was a "Shark fin" style antenna - also with SYNC, just couldn't tell if it had SYNC level III or still II - either way, you will find these vehicles are using parts - variants of older/previous model years. Even changes in the Center Console and armrest versus Package 100, versus 201A (interior trim upgrades and colors) as an example.
When it came to the Engine - be blessed that you have the TDI versus GDI injection - for in some vehicles they use the 1.0L 3-cylinder turbo boost as part of the ST-Line Trim level but in a "non-ST" trim level. So you can have several changes in Brakes, transmission and suspension alone as these car parts get used up.
Could be an interesting end of year closeout "mess" - similar to a competitors - SEE: DART.
Anyhoo, here's what I found...
Went here to get the above...

Good luck. Hope you find what you're looking for...
Since the powers that be usually call out the part as they see it. To locate the actual part you need to know what the called it in the assembly of all other other parts they called Air Cleaner.
So I found this in a deeper searcjh.
Hope this helps!
