The K&N filters come PRE-oiled and are ready to go straight from the box, then once you do the cleaning after X amount of Miles you then add the oil to the filter yourself, and the key then is too add just enough oil but not too much,, because if you add too much you will easily cause problems with your MAF.
I have had the Panel filter on my Benz for 3 years with no problems whatsoever.
I would stick with the Panel filter only, unless you get a GOOD setup just like the one LAMF has. IF not, then just drop in a K&N panel filter and you are good to go.
There is no use getting an open Cone filter that sucks hot exhaust air back into your engine, if you do it, do it right.
