Increased reaction time on takeoff and acceleration,plus the best thing about this filter is that it actually increased my gas milage about 2MPG

The filter came on schedule, fairly easy to install, no modification of any sort needed. No power increase noticed, fuel mileage increased; nothing extraordinary as my old filter was fairly clean. Car sounds pretty much the same. Great value for a permanent filter, would recommend to others.

I had a K&N filter but I don't like the color (dark, looks not very clean). I replaced it with a green filter. I can hear the air flow hissing sound while driving. For me it's not a noise. Instead it sounds very smooth. I still have not got the chance to figure out if it improves horse power and/or gas mileage though.
