Us Carb Filter And Sound Generator Foam

Furstration · 08-04-2007, 04:08 PM

Easy to do...

Sound generator foam

It sits behind air filter but in line

loosen screw and wiggle off pipe.

foam sits inside

pull it out and put the pipe back..

No the foam does not stop gasses from entering the cabin or anything. It's just a substantial sound damper.

The second air filter (restrictive but designed simply to block unspent gas from leaking out when you turn engine off)

Sits over top of US car std air filters/// Just take a flat head screw driver and gently push into the crak and it will pop out easily

Once it's out... Just reseal your airbox with the spring clips.

will do this later

thanks!

Furstration · 08-04-2007, 04:31 PM

VERY easy and the intake sound is great at @4500 and up...

It doesn't change much under that, but when you're on it, it's

Dammmittt · 08-04-2007, 07:11 PM

Nice work. Is it the same on the M models too?

I would doubt it...totally different engine..

Dammmittt · 08-04-2007, 09:23 PM

I know...but if its the air filter assembly they may have that in common...

Furstration · 08-05-2007, 02:52 PM

erm...

You can't pop your hood and tell us?

Jamenrock21 · 08-05-2007, 03:36 PM

There is another foam peice at the other end of the same tube. I took both out and it sounds amazing!!!

lol. I suppose I could.

Dammmittt · 08-05-2007, 06:06 PM

Well...I got lazy and looked up on realoem. The intake mufflers are different and the M doesn't have a sound generator.

Furstration · 08-05-2007, 08:07 PM

I would say too bad for you, but you have the benefit of far more mods than we do

(not that either of these tweaks are mods)

Dammmittt · 08-05-2007, 08:15 PM

I wouldn't call em mods since I bought the car like this

Furstration · 08-06-2007, 01:20 PM

My mistake,

I meant that you have a lot of available modification parts versus the 06-07 3.0si...

We have squat for tuning, almost no exhaust (although Supersprint have confirmed the 05 3.0 stuff works for the 3.0si) or intake...

We're stuck pulling a filter and a foam bung.

But the car does sound a lot better!

X2 and welcome to the FOAMLESS CLUB!

sure, it's a little too much for the top-up crowd, but for top-down folks like me the foamless growl is awesome! My son was talkin to one of his buddies on the cell phone in the Z4 a few weeks ago, I busted out of 3rd with the sport button on and my son stopped talking, (his friend stopped him in mid converstation) then he said to his friend, "what?, oh THAT, that's the Z4 dude!" Later he tells me his buddy was like, "what the heck is that car your in, it sounds like a bitchin V-8 or somethin..."

BimmerZealot · 08-06-2007, 09:53 PM

<-- Foamless and carbon filterless, probably going to put one of the two foam pieces back in it's a little too resonating/droning for me.

FloridaBoy · 08-06-2007, 10:01 PM

Yes, well it's nice that the Z4 gives us options...

Furstration · 08-06-2007, 10:37 PM

I wen't for a one piece...

I was on the speaker in the coupe with my wife...

who yelled "what the hell did you do to the car!?"

em2b96p · 08-06-2007, 11:49 PM

i checked my 04 3.0i and there is no filter above the bottom air filter. im assuming the previous owner took it out already.

i hate surprizes!!!

Your '04 didn't have the carbon filter in the first place.

nyczyang27 · 09-26-2007, 03:48 PM

sorry to bring this post back up but i just checked my 2007 3.0si roady and I cant seem to find the sound generator. Can anyone confirm that the vehicle has it? Thanks.

BimmerZealot · 09-26-2007, 04:27 PM

I have a 07 3.0Si Roadster as well and it has it for sure. Facing the back of the car look towards the right of the engine on the firewall

nyczyang27 · 09-26-2007, 10:25 PM

I don't see it.. looking at the pictures, it should be right on the back side of my intake body but its just not there...I'll take a picture tomorrow morning
