In some ways yes and in some ways no. They obviously dropped that design and went into a different direction. Im assuming it might have had something to do with either a flaw in the design or the complexity. A little more research will help figgure that part out.
Wow, not what I was expecting at all, very different from the S4 setup. Thanks a lot for getting these pics up, like Count said, I doubt anyone has taken the time to look at one of these intakes like this.
Pardon my ignorance, but what is going through your heads when you look at the manifold? Is it already efficiently designed to the point where there isn’t room for modification? I don’t see anything obvious to change like in the S4’s.
You have to look at every part with the thinking that the auto make( engineer) built the part to be as efficient as possible ( for fuel economy and a power range designated by his bosses). There is always room for performance and just general imporvment it might not always be a tremondous gain but still and improvment over stock. Auto makers set outrageous goals and standards then detune the car or truck that is why there is an aftermarket.
The main point is to see where the most can be gained and if the part is even worth playing with or cost effective.
Ok. so it was obvious what wasnt so efficient on the S4 intake manifold, but looking at what we have it is not so obvious, does anyone have any idea?
Could it be how the Vacuum actuators work or could it be the size of the spaces on the Vacuum Shaft?
is the bottom half of the intake manifold plastic, or just painted black aluminum/magnesium?
I’d been wondering that as well, and it sure does look like plastic to me. It also looks like part of the runners and the ports where it meets the block is plastic. Rather interesting if they did go to plastic for part of the manifold when designing/making it.
The bottom part of the manifold is plastic. I am not sure if it is able to be separated, any idea how I could go about that.
From the looks of it… its plastic and most likely mold injected. The S4 intakes have screws on them that you take out and its kinda obvious that they can be seperated. Not sure your intake can do the same thing. Look for a witness mark on the inside. This should let you know if its one piece
hammer?
If that doesn’t work then you know the proper solution. . . correct?
Bigger Hammer
hahahahahaha…of course the right tool in any situation
gotta love the BFH or even the RBFH
I dont think the hammer is going to work. Looks like the manifold is completely made of plastic and cannot be seperated.
I wonder if it is made from the same or similar material to what JHM use for their intake spacer G-10
I wasn’t able to remove the intake off a 3.0 car I looked at today but from what I can see its much different then the S4 one. This isn’t great for the easy steps of doing inside work but this isn’t the end of the road.
For now. I think we need to look at the exhaust and tune as the first big steps.
Just throwing this out there, or rather thinking out loud. I wonder if a B5 S4 or B5 RS4 intake manifold would fit. The B5 has the intake on the front of the manifold and you wold either have to turn the manifold backwards or re-route the stock 3.0 piping to the front.
Pic of the B5 manifold…this is the later one after the '01.5 refresh
That would be awesome if we could run a B5 S4 intake manifold, but the port size of this intake manifold is smaller than the 3.0 so we would have to open that up. Not sure how hard or easy that is to do. Also when it comes down to putting it on not all of the locations for bolting it down line up.
The RS4 one would fit as the rs4 ports are the same size as the 2.8 heads.
Here is my take. The intake would fit but you going to loose that lower RPM power. Its deffinitly a great idea. I say try it. Im sure you can sorce one for cheap
Wow, good thinking. This is what I was talking about earlier, I’m sure some things we run into as performance walls can be overcome with existing audi parts for other platforms.
I’m assuming the b5rs4 would give top end gain, so maybe we can figure out a way to minimize or eliminate bottom end loss. All in good time though.
Anybody interested in an extra IM assembly for testing purposes?

I’d be happy to get it from him and ship to somebody
