Default Plenum Removal: What is This???

I am removing my plenum for cleaning & I'm not familiar with this bolt on tube, it leads to the brake booster.
Is it OK to unbolt it, its seems like its frozen on.
Or should I just keep the plenum in place and clean around it???
Thanks.

That's the vacuum line for your brake booster, soak it in some liquid-wrench if you need to but it screws right off. I find it easier to first loosen the plenum and tilt it upwards and then try removing the brake booster line, gives you slightly more room

Thanks guys.
I just soaked it with liquid-wrench & gave it a big strong heave-ho: it came off.
