While perusing the MBZ diesel offerings on ebay (always looking for the rust free 300TD with blown motor within walking distance to pick up) I came accross a 1985 300D with the air cleaner mounted in the front corner of the engine compartment instead of atop the turbo. Looked like a fine engineering solution to the pesky rattle of the air filter housing, and the engine looks even better than usual with the turbo and intake manifold exposed. Is this a factory setup? A California setup? An aftermarket mod? It sure looks great, and would block the A/C reciever /drier but not interfere with much else. Has anyone seen or had such a setup?
