After more than one week of use I can say that the K and N filter has provided slightly better performance and fuel economy

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.

I've used various high air flow filters for years, normally oil based, and it's become the very first item I add to a new vehicle. Most bang for the buck for sure. After using the aFe Pro-Dry I'll never use an oil based filter again. Nice to handle, no mess in the air box, fit like a glove and AT LEAST equal or better performance gains. Highly recommended!
