Try pulling the air filter element out-it will usually have the part number stamped on the end rubber.  Good Luck, TomC

I have been searching for you because I know there was an article somewhere on the net several years ago.  I assume you have the four oil bath filters like on the 4106 (three on a 4104).

Someone did come up with a plan using the existing oil bath housing with some modification and paper filters.  You just have to find the right size filter yourself using the oil bath as a guide.

Alternatively, you could replace the entire assembly like this guy has done:
