I think the Saab engineers were smoking something when they did this...
They were kind enough to give the car a cold air intake, and this is how they did it:
After getting sucked in by the snorkel, it takes a 90 degree bend, then another 90 degree bend before feeding into air filter. Note that the air filter is friggin' huge, by the way. You can't see it, but that air box is pretty tall.
You may also have noticed that the air enters the box tangentially, and not offset. I'm guessing that there is a circular part of the filter (directly inside the inlet) that is passing a huge fraction of the air.
Oh, and these are 90 degree bends numbers 3 (entering the airbox and turning up) and 4 (outlet).

I now have proof that the stock intake does indeed overload a small circular section of the air filter.
Next up is the AMM. No bends in this picture.
Leaving the AMM, we've got another slight bend, not too bad at all, so we won't even count it.
The little hose on the top is the APC return (R on the valve) line. I'm not exactly sure what the larger port 90 degrees away from it is.
Here you can almost see where that feeds into the compressor. No bends here either, but once inside the compressor it has to turn 90 degrees, and at the compressor outlet, it turns 90 degrees again. Those are 5 and 6.
To help you find your way around this terrible picture, the steel line with the wires zip tied in green sitting on it is the oil source for the turbo, and that squarish looking thing jacked into the compressor housing (right above the left extent of the red wire) is the APC charge (C on the valve) line.
This is the hose leading from the compressor output (bend 6, not shown) and feeding into the intercooler (almost visible at the far left, just after corrugated rubber thingie).
Here is where the air leaves the intercooler. I'm not sure how many bends are present here, because I don't know the flow pattern of the stock intercooler. At the bare minimum, you can see one, so I'll call it number 7.
This is the pipe from the intercooler to the throttle body. Notice the 90 degree bend? That would be number 8.
Stock throttle body. Straight through...
The shaft on the side of the body with the big spring on it is the throttle shaft.You can't see it, but underneath is the throttle position switch. It is supposed to read either "throttle fully closed" or "throttle at least a little open, maybe wide open, I just don't know". It is disconnected and there is a jumper on the two wires that are supposed to be plugged into it. (Damn previous owner!).
The diaphragm is the anti-stall dashpot. It slows the throttle return so that the engine doesn't stall when you let off the gas pedal hard.
The near silver hose goes to the ignition advance/retard on the distributor, the far one goes to the canister in the left fenderwell. Among the other hoses and crap on the far side of the body are the preheater lines and the AIC tube.
On the far side, left you can see the hooter valve hose. To the right of that, plugged into the big port is the input hose leading to the AIC valve. This controls air flow at idle when the butterfly is closed.
I haven't got a clue what the electrical connector is. I'll have to check on it.
Here is the intake manifold. As you can see, each cylinder gets a 90 degree bend entering it's tube (number 9) and once inside the head, another to enter the cylinder (number 10).
There's a lot to see in this one. The big port on the left is the other side of the AIC system. You can follow the hose all the way back up to the AIC valve. The silver hose attached to the same port leads to the fuel pressure regulator.
The smaller port on the top of the intake has two hoses. The big one attaches to the canister in the left fender, the small one goes all the way around the engine bay and connects to the vacuum resivoir for the heater duct control system.
The other large silver line in the lower right side of the picture is just a cover over the throttle cable.
Also, I think that air takes a 90 degree bend down into the intercooler, then two more to head back up, which would bring the count to 13. Anyone know for sure?
