I have resisted buying a K&N filter for awhile thinking that I would just replace the regular filter at the necessary intervals and not worry about the washing. I figured the performance gains probably weren't worth the trouble. I couldn't have been more wrong. I'm not sure if I picked up any horsepower but the driveablity improved tremendously. Even when the the car was brand new there was a lot of turbo surge and some stuttering at full on throttle. It only got worse as the factory filter got dirtier. With the K&N, there was no stuttering and the turbo surge was much more controlled and progressive. The car is so much more fun drive. And that's why I bought a WRX to begin with.
