I received the 2020 air box. Much bigger than the 2019 version. I didn't order all the parts at once so I could see what other parts would be needed. As you can see the inlet and outlet are much larger. The box itself is around 120 dollars and it comes with a filter element.
This should be the list of parts you will need. I think some clamps can be used from the original box, but I included them just to make sure I have enverything I will need. I will confirm the final parts list once I have everything installed. So its about 215 total, but it does include a new filter element.
Airbox - 707800859 - 119.99
Hose to top - 707800861 - 15.49
Clamp - Hose to top - 293650096 - 2.54
Hose to turbo - 707800856 - 31.99
Clamp - Airbox side - 514052924 - 11.49
I would recommend holding off buying this until I have the install complete and verify that there are no fitment issues.
EDIT. Fixed a typo on one of the part numbers and confirmed that everything fits.
