Oh I am so glad that I finally found this. I didn't know what that black square box is called so I had to use different search terms and go through tons of threads.
If the silencer does nothing more than sound-dampening, then I want to remove the whole things. I thought it was there as a pre-filter filter to remove water and other debris so that they don't even enter the intake box. If that is not the case, I will run a straight pipe from the intake duct to the intake inlet (?).
You found it! Do away with it and you will be happy!
Just checked the duct tape that I used about a year ago to block the holes inside the intake silencer. The front edge of the tape over the first hole was flapping down in the air stream. I removed it of course. Now to decide if sticky back aluminum would work longer. Anyone check theirs lately?
If you are going to redo it, remove the box and wash it thoroughly, and if you are a bachelor like me just knock the major stuff off with a grease cutter and put in in the dishwasher for a scrub cycle by itself. You will get a clean bond with that aircraft style or muffler repair style metal tape with its epoxy type glue.
I did this a few weekends back. I rinsed the intake, swabbed a blue towel or two through to remove any dust/dirt and dry it off, then used the silver sticky aluminum tape. It's a little tricky to get *just right* but not impossible. I smoothed it out with a large Philips head screwdriver wrapped in a piece of blue roll.
Worked perfectly, sounds great. Throttle response even improved a noticeable amount. I like this change a lot. Thanks for the info, guys.

Me and some guys in Germany modified the Intake Silencer .
Now I saw at realoem that american MINIs have the same "thing" installed.
What we did ... we modified the part #12.
1.
Remove the silencer.
2.
Look inside and you will see these holes on the top of the silencer.
3.
Take some tape and close the holes with it.
I used a srewdriver to fix the tape because there was no chance to get in with my hands.
4.
After mounting the tape it looks like this.
After that re-install the silencer and have fun.
Between 2000rpm and 5000rpm it sounds really great!

Does anyone have the pictures that were once here (or have their own)? I've always wanted to try this taping the silencer thing, but I have no idea what the intake silencer actually is or where its located
I replaced that box the other day. I had some extra parts from a previous air system. I am sure that one could go to Home Depot and pick up the right size pvc or abs pipe and do it. Pretty much one 90° elbow and some straight pieces.
I cut off the inlet from oem plastic piece for the airbox and cut off the outlet of the silencer box, couple hose clamps and rubber hoses. I am actually thinking that pvc or black abs pipe would insulate the air going in rather than hot metal pipe better.
