I did what you said and pulled the SBF#2 fuse for about 45minutes. I then put it back and my CEL was still on. I guess that trick doens't work on the newer Legacy's. I'll have to disconnect the battery and reset my stereo setting now. That better turn the CEL off or I'll have to go back to the dealer.
BTW-The K&N filter is awesome. I didn't expect to much but did notice a difference. Especially throttle response, it doesn't hesitate at all anymore. From any complete stop the car moves instantly with a touch of the pedal. The acceleration is much more linear too. It's no AEM CAI, but it's something.
