Replacing the OEM filter immediately increased my fuel mileage in my Honda Fit 2.5 to 3.5 MPG everyday. I use this car as a delivery vehicle and keep track of the mileage every day. Impressive

Got it. Put it in. We'll see how power and mileage are affected. Thanks.

I've had my K&N filter now for a few months. So far, maybe seeing a slight bump in performance, and no gain in fuel mileage. Sticker looks nice though.
