Thanks for that info. So these two sensors can be left plugged in but just hanging freely in the engine bay and not actually plumbed into the intake tract with no negative effects?
For info, those sensors are B28/4 and B28/5, and they're pressure sensors, used to prevent turbo over-speeding with blocked air filters.
There's also a pressure sensor between the charge cooler and the throttle (B28/5), and another on the inlet manifold itself (B28/6).
They're held in with two small screws (rather than screwing in themselves, like many other sensors). Therefore they're quite easy to fit, but not many people bother.

Thanks for that info. I'm almost done with my intake setup and had one last question.
In the pictures below, I assume that this was a breather hose for the stock intake box that's only on the driver's side? Is it safe to disconnect this hose and then cap/tee it off at where I'm pointing at the in picture?

Air filters are used for air inlets. The pipe in question is an air outlet that feeds crankcase blow-by to the engine air intake, so the engine is kinda sucking the fumes out. Probably not very important. Just don't cap it off, or crankcase pressure will build up and cause oil leaks etc
