How's the air flow of something like the Fram WA8039? Adequate? Surface area looks quite a bit smaller than stock.
If air flow is so-so, I'm not against install 2 of em, side by side or so, feeding into one air intake tube. Kinda dumb, but I like kind of dumb.

Not a person that is good at math anymore. I think if you take the rpm and divide by 2 and multiply that by the Engine displacement you would get cubic centimeters (or liters) pre-minute and convert that to cubic feet per minute.
Some filer sites list the cubic feet per minute the filters. I am not sure Fram shows that in their site.
However, if you look up the Filter Number you will find it is used on Ford Pickup Trucks and Vans that have larger volume engines then the 617.952 is. I assumed that means if it is sufficient air flow to a larger engine then it ought to be OK for the smaller volume of the Mercedes engine.
I don't know if any of the Ford engines are turbocharged. I also don't know how much extra cubic feet of air a turbo needs when it is boosting.
Someone with better math skills can calculate how much more volume would be compressed into a cylinder when the turbo is boosting at X number of pounds over atmospheric pressure. And work that into the formula I suggested.
