The twin pipe induction is what I would have really liked on MY 6.9.
I have a cheaper, somewhat 'ersatz' system, but from a breathing point of view, is still superior to standard.

The all alloy air cleaner box on my 6.9 is from a w126 560 also.
There is no room for twin induction trumpets in a 6.9 engine bay. Both trumpets were simply removed, extra airways cut out of the sides of the box and alloy gauzed over, riveted into place.
The alloy air cleaner box lid was buffed shiny, and sprayed with clear laquer, to retain the bright metal shine.
Now, the engine bay of my 6.9 looks to be a brighter and less dingy place, and I think the engine would be a little happier, with slightly easier breathing.
I probably have 4x of the single choked down trumpet area available for air flow into the standard air filter.
I have retained to original black painted 6.9 air cleaner box, with the single choked down trumpet that allows for the chain cover clearance.
The 450 diff, new stainless steel exhaust, small induction improvements, and new 225 60 VR 15 tyres with 1.6 % less outside circumference combine make the old girl much more throttle responsive, and an even more pleasant and satisfying car to drive.
A bonus is that with the 450 diff, there is less torque converter slippage with normal driving, resulting in slightly better fuel economy, in spite of the slightly higer revs for speed. A negative is slightly less top speed, but how many of us get to do 235 km/hr on our roads?

Mine as you would be aware is a lot more responsive than standard. And yes 560 will fit. by moving Air con line and battery both of which I am doing. As air needs complete over haul has not worked for around 20 years. I have larger throttle body to fit. And motor is being done in a few weeks.

Air Con O/H... There is specialist in Sydney who supplied me with a Seal Kit and Bearings plus a new Clutch with Pulley to rebuild my noisy Compressor. Can't remember the make of the Compressor , it came as a Mercedes optional and is a twin Piston type. Now works well , even if it is a big drain on the Engine. With modern units , as on my New 1.4 Mk 7 Golf , the engine hardly notices.
