What is this hose?

Level: Amateur (so please bear with me on these terms)

While working on changing my ignition coil (after Googling and looking for DIY), I found this hose that looks like it goes from the air filter. I took pictures to map how it wraps around.

No idea what it is and if it's important.

Thank you.

That other end attaches to the intake manifold somewhere. It isn't supposed to be free hanging
