2001 c320 leak sound .
This was when the car was idling, if you listen closely and put the video on HD you can hear when i push the brake down the sound goes away.

It does not sound expensive.

You can fit a K&N air filter if you want to. I would stick to stock filters & worry about maintaining the rest of the car. A breather, as an example, takes oil fumes from the crankcase to the inlet system to be burnt off by the engine.
The first thing to diagnose is where the noise is coming from. It might not be a hose.
You sound uncomfortable about working on your own car. You have a 2001 model & they were known to be more troublesome although Samaritrey's 2001 has been a good car.
Maybe you should take it to a good independent shop to sort out.

figured out its the huge nipple on the brakes looks like an accordion check out the video and let me know what you think

It might just be engine noise leaking through a hole in the boot but you might have a master cylinder leak or a vacuum leak on the booster. Does the car use any brake fluid?
