Anyone know which would be a better oil filter? I can't seem to find a K&N oil filter anywhere. Not even for the 2011 or 2012. I can find Mobil 1 all over the place. Is there any advantages over one or the other? I just know I don't want a cheap piece of crap in my car. I have narrowed down to these 2. STP I hear good things about as well, but haven't heard much about the K&N and Mobil 1. I would greatly appreciate the help.
