removed it 1-2 months ago (already had the k&n drop-in filter), noticed an improvement on engine response, it just felt like it reved easier when pushing accelerator pedal 1/4, maybe it was super dirty (didn't notice). Obviously didn't notice any performance gains when full throttle.

no change in mpg though.
