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 (?). :nod:

You found it! Do away with it and you will be happy!

Thank you, Ive! You definitely pointed me in the right direction. :thumbsup:

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?

Yep, I checked my aluminum tape about a month ago, still stuck down hard, so it has been about a year and 20k miles in place.

Thanks, Tuscon!

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 :grin:.

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!

Chris :grin:

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. https://cimg5.ibsrv.net/gimg/www.nor...77ad063ade.jpg

I also drop a K&N filter in the oem box.

GimmeBoost 07-29-2018 02:40 PM

How did you seal the piping to the air filter box?

AzBluesman1962 07-29-2018 03:01 PM

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.
