Maybe I'm wrong but.....When you switch to the K&N filter, the filter channels more O2 to the engine. Subsequently the oxygen sensor senses the extra O2 and compensates by increasing the amount of fuel to compensate. therefore dropping the mpg but increasing the horsepower.

I was going to do the same thing for the increased power but a tech friend explained it to me and I decided that my power is fine...I need the mpg right now....try switching the filter back and do another mileage check....good luck
