Hey. I just put in the OC. I didn't hear much difference... and wasn't looking for anything else, but DAMN if I don't feel better throttle response at low RPM. Even the dead spot I've been hating at the bottom of 2nd gear at WOT is gone.
Thanks Jim!

It is doubtful that the cap will get sucked into the engine
Why?
Because if it did become dislodged and sucked into the intake, it would get stuck in the throttle butterfuly valve before it went into the intake manifold. it is also too big to fit down one of the runner tubes. Where the cap is in the airbox, it is not hot enough to melt the cap, and it is assumed that the cap was inspected for tears or holes before it was installed.
But never say never, I would think that one of you reading this will figure out how to get one stuck in the engine

I think you pretty much need to go WOT to really hear it, but with the system you have which screams real nice already...I'm not sure you'll hear much difference. Interesting on T/Response however, you are the second or third person who has said that.

Resurrecting a very old thread. Anyone happen to have an orange cap laying around, or know of a replacement that will work? Please email me if you do.

A 1-1/2" pipe cap works great for sealing the airbox and taking the Hemholtz resonator out of the circuit, but really more for use in conjunction with an silicon intake hose... The silicon hoses can be had inexpensively on eBay.
Love the intake sound!

The Fabspeed version actually has a cap assembly to fully replace the stock resonator chamber to gain additional interior Airbox volume.

Just ordered a black silicone hose off ebay for $20, too bad its shipping from China and is going to take two weeks to get here. I'm so impatient once I get an idea in my head...
Planning to cap the helmholtz resonator with one of these (recommended on another thread):

If you know what length/Diameter/Bend Silicone tube you need, these guys are great. I've bought several for my M3 over the years.

Got my hose off eBay for $20 and a cap from Home Depot for $8, sounds great combined with the gundo hack. Gives it just that extra bit of growl, now I'm very happy with the exhaust sound.
