Hello
Regarding the air intake, the recommended air cleaner is the Stealth Air Cleaner Kit ítem # 170-0200
https://www.sscycle.com/products/stealth-air-cleaner-kit-without-cover-for-all-x-wedge-engines/. This ítem # 170-0200 is the exact one needed for my 2019-2020 3-Wheeler. If yours is also new, this is the one you have to buy. I can't tell you for the old ones.
Then you need a cover. And for the cover, you have many choices from S&S:
Item # 170-0121 is the chromed Muscle Cover
https://www.sscycle.com/products/muscle-cover-kit-for-stealth-air-cleaners-chrome/. And it's the one used by G56 if I'm not wrong.
The item # 170-0120, the one you indicate, is the chromed Domed Bobber

Following this link you have all of the Stealth Air Cleaner available covers.

Personally, I don’t have the Stage 1 (not “legal” in Europe, at least in Spain) but the Stealth Air Intake with the chromed Muscle Cover
https://www.speedymarmots.com/hangar-works-9-change-of-air-intake-kit/. It's the one I liked the most. And really easy to install.
