A K&N FILTER ALLOWS YOUR CAR OR TRUCK TO BREATH SO MUCH MORE FREELY. THERE IS JUST NO COMPARISON.

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.
