Dude go ahead and order the two intake boots. No way they survive bring removed to install the BBTB.
Fudge, I thought they might survive. Any other parts likely to break in my extrication of the small boy TB?
Anything else I should replace while I'm in there? Tutorial videos show it is maybe 30% more involved than I had previously thought to get access to the throttle body.
The only other concern would maybe be the DISA gasket getting damaged during removal, but you're rebuilding that so you're good there. Those boots are constantly flexing since they're the link between the vibrating engine and the body-mounted airbox. Given their age, I'd expect them to be worn out and ready to tear if you look at them wrong.
A new throttle body gasket is cheap and so is the iacv grommet.

So added items to purchase:
- Upper intake boot (13541438761)
- Lower intake boot (13541438759)
- Throttle body gasket (13547504729)
Any thoughts regarding replacing the "intake boot connecting ring" (13541438760) or having one on hand due to risk of it breaking during disassembly?
Any other hoses or things I should consider while I'm in there? I've seen people talk about the plastic elbow connector on the upper intake boot, or cleaning the ICV (preventative cleaning since I have zero ICV issues).
As always, appreciate the help in advance!
Oh yeah the F shaped connector on the vacuum hoses coming off the intake elbow. That guy can break, but usually it's the old vacuum hose that connects to it and goes to the fuel filter. The car will run fine if you break it so I'd just wait and order the part later if it happens.
The plastic sleeve between the two intake elbows is solid. Shouldn't be a problem there.
Okay, doing some research, the hoses and F connector are not accurate on RealOEM diagrams. From this Bimmerfest thread, it seems like these are the correct parts, but would love if anyone could verify
