Hi Subie fans. Just bought a 2012 WRX and loooove it. I used to have a Honda Prelude and does my own oil change. So the question is, where can I buy an OEM oil filter for the 2012 WRX, most I've seen indicates that they're compatible from 20xx to 2010. Also is a OEM oil filter all that important or can I get something like K&N made?
