My car has so much blow by that paper filters are saturated with oil in 5 minutes. I tried a K&N stock replacement, which sucked to clean after soaked in engine oil. So I cut the tube that runs from the scoop to the air cleaner and stuck a cone between the scoop and air cleaner. Now that I know of different oil seperating ideas I might be able to use a paper filter with the oil seperating being done outside of the air cleaner. I did not do this for power, thats why I got an E420, and I know that K&Ns are not good at filtering, but I don't care because the engine seems like it only has 1/2 compresion anyway. I did it because it is easier to clean.
