K & N drop in filter

Here's my drop in filter replacement for the oem lame paper type for the Forester. My concern is it is oiled and I have read that some of the oils will go to the MAF sensor but I have been using this for about 7 months now and all I can say is "Great". Great to the fact that my fuel consumption now is 32~34mpg highway. What more can you ask. Nevermind those saying negative comments about it, they are just sourgraping.

The part number for the Forester is 33-2304.
