Honestly at only $1000, I can see this being a relatively decent option. It's something that has aux ports and a fuel rail is relatively decent. Most PI spacer kits are already at a similar price point.
I'm thinking they're probably reusing the Wagner core like RK, or China's started making B58 intake manifolds
Definitely this, I think the better rule is that if you're paying over $3000, might as well go EOS, otherwise stay stock or go RK.
Not sure if I'm reading this right, but AFAIK only post 06/2020 ECU's need to be sent to Femto to get CustomROM flashed, otherwise pre 06/2020 ECUs can get BM3 CustomROM normally flashed, just like EcuTek RaceROM
I don't own one, but if you search around the Gen 1 B58 forums it has a good rep. Pure used to he a great option but recently a lot of people have had their turbos blown. Pure offers a replacement, but getting a blown turbo is risky at the end of the day, especially if you're getting your stock...
AFAIK they just came out recently on brz-zzz.com. Not sure if he's distributing them yet but they look nearly finished, seem to be production models anyway.
Might be worth waiting on MHD+ to come out this year if Reflex integration is worth anything to you. Otherwise it's sending your ECU to Finland to get BM3 CustomROM flashed, and then sent back again to get MHD+ flashed.
Not sure if this is related, but chinese top mount manifolds just dropped

They're on ebay for a major markup by resellers
I'm fairly sure this is the same thing:

I just found it by googling " 9496757 BMW"
Not sure if you can get it locally though.
Fire Extinguisher Holder: 9496757
Fire Extinguisher: FL949675601/21B193JJ0238
These are for the GCC/Middle East spec cars, so the actual fire extinguisher might vary. The mount/holder itself is probably universal though.
