Oops, I just found this thread! You must have posted during my internet blackout before I got it at home.
HERE is a recent picture of my air filter setup. The one in the picture greasybenz posted was waaaaayyyy too small and was a pretty bad restriction. The later picture in my gallery was a much better filter.
"BTW, the stock design is a cold air system, which most of these kits are not."
I have also realized this and have replaced the custom setup with a stock filter housing from an 80' 300SD. I chose this because it does not have the oil-seperator built into the housing. Since I have yet to find ANY oil-seperator that works worth a cr@p, I'm venting straight to the atmosphere (road draft).
The second reason I chose to switch back to a stock filter housing was to make room fo a future intercooler where my filter was. i could not find a practical way to keep using the big filter with the powersteering pump in place.
I'll take a picture on sunday and put it in my gallery.
