S54 Engine with plugged ingots

So, how much lower is the idle air feed pipe now?

Did you see what I mean about the idle valve fitting into a pocket on the backside of the airbox? Prevents lowering it unless you mod the airbox...

The blue tube shown in Ron's opening picture turns out to be the highest point of the engine (as far as a strut brace is concerned).

That was why azzman had to come up with another pattern of bar.
Ron too has been working on one.

While I had the airbox off my car I tried a couple of tricks to lower that tube. Extensive work required no matter which approach you take.

To really answer your question:
The blue tube introduces the idle air to the throttle bodies (downstream of the butterflys).
That "device" under the blue tube is a valve that allows the air to flow through.
Underneath the valve is a rubber tube that gets its supply of air from the airbox plenum, downstream of the air flowmeter.
Naturally, the injectors supply the fuel for atomization.

Too bad we need to keep the air flowmeter in the circuit, some nice velocity tubes with "socks" on them would really look nice...
